Title: Need help with wiring ID for radio!!!
Post by: pintogirl on April 10, 2009, 09:32:40 PM
Hey you wiring guru's!!! I need some assistance with some wire identification!!!

What I have in this pic is the AM radio. The cut wires are speaker wires. I know this because they match up with the speaker wires hanging under the dash!! :) The plug is the power to the radio.

Simple enough right? Not when it comes to a hacked wiring system under the dash!! LOL Of course, the only thing I can't find is the power plug for the radio under there!!

In this pic. you see the speaker plug bottom right, but what is the white and purple wired plug? 2 wires are going to that one plug. One is purple and white and the other just white (I think? LOL) The PO has hacked into it and has the ACC wire to a CD Player hooked to it!

(http://i106.photobucket.com/albums/m247/myhrdly/Pinto/IMG_6606.jpg)

The next pic is a plug that comes from the glove box side. It has a hot wire tied into it and also a wire that goes to that plug you can see way towards the back. I believe that is going to the cig. lighter! What does that plug go too???

(http://i106.photobucket.com/albums/m247/myhrdly/Pinto/IMG_6607.jpg)

Last queston, no pic though!! LOL  IF the original wiring is intact, where would the radio underdash plug be comeing from?? I can't find any wires that match the color of the wires on that radio. In fact, the wires you see in the pics are the only loose wires comeing from under the dash.

I appreciate any help!! I am trying to get this radio back in, somewhat the correct way!! If all else fails though, I will just use the "Hot" wire from the CD Player that has been pushed into the fuse box! Oh, speaking of, the plug you see in that last pic that has the ACC tag on it, goes to the cd player. I havn't disconnected the wires yet. Want to make sure I am ready to reninstall everything before I do so!!! :) I'm very forgetfull and this helps me remember where the speaker wires and such are!! LOL

Thanks

Kim,

My car has the original wiring under the dash but I don't know if it will be the same being a 77. It is 11:51 pm here in Ohio so I can't look at it at the moment lol. Anyways I can take a look tomorrow, but will take a quick look at the Ford Pinto wiring diagram books for 1976 & also the 1978 to see what I can find. I'll post my results.

So if I remember correctly, the there are two power wires to the radio.  One is to power the radio and the other is for the light when the headlights are on.  The radio grounds to the dash when the rear bracket is used to secure it to the dash.  If you do not have the bracket, you will most likely have to run a ground wire.  It is hard for me to remember/ tell which wires are for the radio from the pics.  I would maybe ohm out the spare wires to see which ones are which.  The power wire for the radio has to power on and off with the key.  The light wire will only power on when the headlights are on.  I hope this helps some.

OK Kim, here goes nothing.

According to the wiring diagrams for a 1976 the Hot wire for the radio is a yellow with a black tracer. That wire runs to the fuse. On the 76 it is fuse 3. I'm not sure what fuse number it is on your car but that will give you some idea. Like Tigger said the radio grouds through the bracket, so you just need to run a wire to ground from the back of the radio if you don't have the bracket.

The illumination is a blue with red tracer.

I don't know if the colors are the same on your year but figure this might help you out.

Ok, that kinda makes since. Without going back out and looking at the radio, I beleive the blue and red wire does go back to a light or something, I know it kinda makes a loop back into the radio!! So that would mean the black wire is the hot for the power of the radio.

Would you agree that most likely there was a plug in the dash that matched that of the radio?? That is what is confusing me. There doesn't seem to be any type of radio plug or wires hanging loose under there! Just the ones I have in the pics above are hanging in there.

If the light for the radio is supposed to come on with the headlights, I will try to look up under the steering wheel more, to see what wires my be heading toward the radio from the area of the headlight switch!!!

Ok, that is what I was thinking the blue and red wire was!! Thanks for the confirmation!!!

I will go look at the fuse panel tomorrow to see what I can see! I will look for the yellow and black wire.

I do have the bracket so I can ground it to the car! I will need to be grounding the 8 track speakers and amp too, so I could always make a wire to ground the radio, if my bracket doesn't reach, like I think it will!! LOL

Thanks for the tips on the wire colors. I hope that the 72 is the same as yours!!!  :D

Lol, that would be good if it is. My car is a 77, and the wires match both my 78 & 76 books so it could be the same color. Glad my dollar books helped you some. Good thing I got them from Carlisle last year.

Post by: pintogirl on April 10, 2009, 11:26:25 PM
I'm hopefully going to be glad you bought them too!! LOL

I would have went to the Green Machine and looked at it, but I have radio already in there, so I didn't want to pull it out1! LOL In fact, that is the car the radio came out of, so I bet the plug is in there too! LOL I can't remember now if I unpluged it or not. I know it did work. Hmmm, thinking about it now, I may have to go pull that radio so I can see where the wires are! Duh, didn't think about that!! LOL

Ok, you guy's just witnessed a blonde moment!! LOL Forgot all about the radio coming out of the Green Machine!! Hey, but at least it gave you all something to think about!! LOL  Oh, and to kinda defend my blonde moment a bit, I did go upstairs and look at the dash from the yellow donor pinto, but didn't see anything, it had newer style Ford radio in it, not original though! LOL On another note, it had a underdash cassette player installed in it. I could install that under the 8 track player!! LOL
Title: Re: Need help with wiring ID for radio!!!
Post by: r4pinto on April 10, 2009, 11:29:37 PM
LMAO!!!!

Thanks Kim, I needed that. To be honest I didn't even think about that, even though I know you have three other Pintos, not including the Pinto in a box. If you were out here I would tackle the wiring, as I LOVE car electrical. Harold II is proof of that  ;D

I believe the 72 beater I had last year had a plug from under the dash that the radio plugged into.  If someone installed an aftermarket radio into your car, chances are the plug was cut to make the install easier.  

In your third picture it looks like there is a left over harness from an aftermarket radio.  The plug has a red ACC flag on the red wire and the plug housing has a 1804 number.  I would maybe trace the wires off that plug and see if you can find the correct ones to the radio.

Yes, that is an aftermarket radio plug! I left it there till I can re install my other radio and equipment!! They have the ACC wire going into the white and purple plug in the pic above. They have the yellow power wire for that plug, plugged into the fuse at the fuse panel. There is no other wires, that I can see, that have the apperance of being cut to install that aftermarket radio. That is the confusing part. You would think I would be able to find the "original" radio wires, even if they did cut the "original" plug off!!

I am correct on thinking that "if" original, there would be a plug opposite of the pictured above radio plug, in the dash somewhere, right? There wouldn't be 2 seperate singe plugs that plug into that 1 dual prong plug on the radio??? What I'm trying to ask is, could the original have the white and purple plug going to the blue and red (light) prong, and then have another plug that went to the power prong???

I'm going to PnP tomorrow, and they had a later model Pinto out there, I will try to see if I can get the plug off of it, if it is still in the dash!!! That will help too. I don't want to have to cut the plug off of the radio!! I know that would be the easiest way! LOL But I am trying to keep it as original as possible!!  :) If I can find that plug, atleast I will have the wires to run to a hot, and then to a headlight wire (which may be another topic to talk about!!! LOL)

Kim, if you can't find the original plug at the junkyard here's an idea.. You can use the bullet connectors you find in the store. In case you aren't sure what I am talking abut here is a link to some at autozone. They are available in male & female styles.

First off I need to thank you all for your help!! You guy's are great!!

Today I went to the wrecking yard in search of the plug I needed, but to no avail! So when I got home I took the am radio out of the grey car. Once it was out, I then realized the radio I was going to install was not the right radio for the Pinto. Well, atleast for the Pinto I have!! LOL  The correct AM radio for my car is the one that only has one hot wire and the speaker wire.

I tested the radio that I had just pulled out of the grey car, and it comes on, but no sound. So I figured I would just rig some wiring up to put the "wrong" am radio. Well, I decided to test it, even though I though it worked when I pulled it out of my  Green Machine. It doesn't!

So, long story short. I am going to just install the 'correct' AM radio, that doesn't work either, into the Pinto just for looks. I will then hook up the underdash 8 track so I will actually still have music.! I can look for an AM radio that works, later down the road!!

I would install my Kenwood cassette deck, but I am going for the "period" look.  ;D

Thanks again for the help!!!

According to Wikipedia: From the mid 1970s to the late 1990s the cassette deck was the preferred music source for the automobile.

It would have been very common for a second or third owner to take a newly-purchased two-, three-, or four-year-old car and update it with the latest stuff, such as a cassette player.  I think that an older "clunky looking" cassette player would be "period correct" for you.

If you are interested, I believe I have a couple early Philco Am radio's.  When I feel better (sick with a cold) I will dig them out and see if they are still working.

Post by: pintogirl on April 11, 2009, 09:31:36 PM
Thanks for the offer on the AM radio. I think I will go with the non working AM radio for looks until after Knotts, then I will put my cassette deck in there. It will work out better with it in the long run anyway. The way I have it set up right now, you can't put the car in park when the 8track to cassette adapter is in the player!! LOL And it will probably have a better sound then the way I am running things now! LOL I just used some speakers we had laying around and I think they may be somewhat bad. I'm going to go to Best Buy and get some new 6x9's before next weekend to see if I can get a better sound. Course I guess you can't expect to much from an 8 track and a 40 watt amp!!! LOL  I'm used to 250 watt and up amps!! LOL

Here is what it looks like now!!
(http://i106.photobucket.com/albums/m247/myhrdly/Pinto/IMG_0217-1.jpg)

I'm hoping that once I buy the new 6x9s, I will at least be able to turn it up a bit louder then what I can now without it distorting the speakers!! I'll probably go buy them Monday after work and will report back then!!

Kim, I like how you have the radio setup. Does that booster really help and where can I find one?
Title: Re: Need help with wiring ID for radio!!!
Post by: pintogirl on April 11, 2009, 10:51:23 PM
Well, when I tested the booster to see if it worked, I could tell a difference in the volume of the radio. The way I have it hooked into the car, the speakers that are hooked to it, are not hooked to the player directly. So no sound comes out of those speakers till I actually turn on the booster. The other smaller speakers have sound coming out of them at all times but they are not hooked to the booster. I didn't want to run all 4 speakers on the booster, but truthfull, I probably could have as it isn't as powerful as a 250 watt!!! LOL

I hooked things up that way because the 8 track is set up for only 2 speakers. I hooked the 2 "front" speakers into the "input side of the booster, so they wouldn't be boosted. Then I hooked the 2 back speakers to the output side of the booster.

The only thing I noticed, that I didn't notice before, is it seems that the 8 track tapes, at times, seem to have background songs, like a song is bleeding through. You can hear it when the song is ending and getting quiter, kinda like you are hearing the song on the other side of the tape, per say! Not sure if that was there before and I just didn't hear it because I only had 2 cheapy old speakers.

Another thing I am kind currious about. With the 8 track, it wants the speakers grounded to the car. I did this on the front speakers and the input side of the booster. On the output side, I hooked the ground to the ground wires and the positive to the positive wires on the booster, I did not ground these to the car. I did go to the back and tried grounding the speaker to the car, without disconnecting anything, and it just turned the speaker off. I didn't try disconecting the ground off the speaker, and then putting a ground wire to the car though. The reason I mention this is, I'm wondering if because I hooked the wires to the booster, the way the booster calls for, insted of how the 8track calls for, could this be causing my "bleeding" through of music?? Or, is it just because the 8 tracks are old? LOL Confusing huh?? LOL  So, on the input side I have all the ground wires tied together and grounded to the car. On the output side I have the ground wires from the booster hooked to the ground wires on the speakers!


Forgot to answer your question. I found the Booster at a PnP, it was in a Pinto!! LOL Not sure if you can buy these new or not. I needed something with out RCA jacks, and I'm not sure if they still make booster without the RCA jacks!!  Now that I think about it, when I install my cassette deck, it has RCA jacks! LOL So I guess I could hide a bigger amp in the back somewhere! That is if I don't change my mind on installing that deck!! LOL

Hmmm.. I guess I'll have to check eBay then. The junkyards around me only have newer cars in them. I guess I just need to move to california lmao. Nah, my GLHT & Pinto would prolly fail inspection & that would be bad.

Yah, I just really lucked out on this one!!!


The smog law is the reason we decided to scrap the 77 Pinto. It was not worth getting a brake, light and smog inspection to get it revived, and then it would have a junk slip on top of all that!! Just not worth it! It will live on in others!! LOL
