Electrical help needed
Hopefully the last thread on this subject.have gotten good advice thus far and fixed many problems but some still remain. My dash lights now work,radio is functional and rear courtesy lights work but only with headlight switch rheostat. My under dash courtesy lights do not work even with new door switches and wiring hooked up correctly. Any suggestions where to look? Second thing is stop lights work but passenger side gets brighter when pedal pushed but driver side gets weaker? Signals worked previously but now do not. Flasher works fine. These small issues are more than aggravating and hope I don't need to take dash out again.Any comments will be welcomed as I'd sure like to drive this big block 68 Thanks

I removed all that courtesy light crap years ago, the orange wire is always hot, and of course fused.....the white wires are grounded by the door switches.....
in the rear, methinks you have a bad ground coming off one of the tail lights.....they are lighting up a bit because of finding a ground through the other side, so act weird.....looking for a black wire, going to the frame.....

As far as the stop lights I would measure the actual voltage you are getting from the fuse box with and without the pedal pressed. If you are getting a full 12 volts both ways then it has to be a ground issue.

lighting
It sounds like you still have grounding issues on the courtesy lights or the courtesy light relay is out. With the courtesy light bulb in place touch the side of the bulb to the steering column support or with a known good ground and see if it lights up.
