I'm not worried about the instruments right now. I have just the harness at home and am trying to figure out ignition on, always on power, etc. Hoping the manuals I have coming include pinouts as none of the other diagrams seem to.
There's the power for the stock ignition module, oil and water switch wiring, etc mixed in that I need to eliminate. I should've labeled all the plugs before I ripped the motor out and gave it to my dad
