Okay so new thread new question.

Is there a wiring diagram online or does someone have one they could post? I am looking for one for a 1975 H/O W30. Someone did a hatchet job on the wiring it looks like to accommodate an 8track player. I will have to run all new wires for it but am not worried about that since I can just run my own. I have an issue where if the radio is on and I turn on the headlights the radio fades out or if the turn signals are on and I turn on headlights the turnsignal stops working. Same with windows, truck light, radio, dash lights etc. I ran a battery tester and the battery is getting 14volts to it constant and under a load it drops to 12. When the load stops it takes it a second and then goes back up to 14 again. I think I have a ground issue but if anyone has any ideas I am all ears.

The wiring diagram in the 1975 Chassis Service Manual posted on WildAboutCars has one, but it's in black and white.

Better than nothing, though.
