I'm not in the mood to start cutting up my wiring just to make LEDs work. I have some other ideas to try. With flashers on and parking lights off, I'm going to pull both red leads to the rear tail lights and see which side is hot (or if both are). I suspect it's going to be the bulb side, bleeding over from the flasher circuit - otherwise why would the license plate and dash lights be blinking and not just lit up.

I think I will pick up a 1157 socket and temp wire it to the pass side tail light flasher circuit with a 1157 bulb and see if the extra load makes any difference.

Then look at the major harness connection plugs - especially #27. When assembling the car I had a parking light problem at the front and finally found two wires mispositioned when the harness was assembled. Reversing those wires to match the wiring diagram straightened out all my lighting problems. But - maybe there is still something out of whack there.

I can't see how the dash light circuit could be backfeeding anything as it's basically a dead end circuit and supposedly doesn't run through any harness connections so I think I can ignore it.

See what happens.
