Okay, so maybe I got a little ahead of myself
After ripping up the old harness I figured only a few wires here and there needed to be removed/replaced so that's all I did. Figured out the starter had absolutely nothing to do with what I was monkey-ing with but was actually just remote wire on the solenoid switch for the starter had a crappy connection and my pulling on the harness loosened it enough to get it to loosen up.
So I fixed a few wires, put a new power wire lead on the distributor because the old one was barely even on the terminal and was all hacked up, and I also redid the battery ground to beefier wire (pics tomorrow!).
I really want to put the rear valence on the car but i don't see much point if I'm going to have to continue to mess with the fuel pump/fuel lines the quiet the vibration I'm getting. I'm thinking of just replacing all the hard fuel lines with rubber compound ones to see if that takes care of the rattle. Some of the fuel line is rotten so a section has to be replaced anyways.
I also need to redo the alternator lead because it's somewhere around a 12awg wire trying to carry a claimed 75 amps. Actually. Come to think of it. I spent all that time under the hood and I have no clue how the hell the alternator is charging the battery with the current wiring setup. Whatever, i'll figure it out tomorrow.
