get rid of that dimmer switch. theres an internal connection going on inside there that shouldnt be. easy to change if youre a contortionist and have patience without taking out the whole dash. loosen the gauge cluster and wiggle the drivers side out til you can see the screws on the dimmer. use a stubby screwdriver to remove dimmer screws,,,,, then reverse to install!
I been damn lucky with my 70 RR wiring. everything in that car works electrically...well...the pissers DID work until i rebuilt the dash. now they dont for some stupid reason. i somehow lost power to the button....and cant seem to locate the prob......not worried tho...the car never sees the rain...and ill find it eventually. ....when im feelin froggy and want to be bent like a pretzel.....aint easy getting 6-5 inches and 270 pounds under there.....i need to go on a freekin diet im thinkin !
it's like helping give birth to a sharp octopus in reverse 3-4 times depending on how you manage to measure everything. my advice is to keep the old harness for reference on length and make sure the wires are warm before you try and move them about when all bundled together. also don't black tape them til they are in, use zip ties to let them flow and move into place. and most importantly, test everything before you install it. tracing wires sucks!Time to find small friends who know electrical. I may take yoga to prepare for my switch out of the old harness.:headbang:
