Steering Column wiring
I acquired a GM steering column but the wiring harness has been cut. How do I go about finding out what wire is what? Where can I get a wiring diagram for it without knowing the end application?
Thanks for your help.
can you tell what car line its from? chevy, olds, etc. if you can tell that and guess the era from its appearence[early 70s, late80s.] try to look up a diagram from a random car from your best guess. the color code and wire positions shouldn't vary to much from car to car, this should give you a basic start. good luck.
HEY FRED: Send me a FAX number or mailing address. I have a generic GM code out of a old mag somewhere I can send. Also local library in reference department has books that have complete wiring diagrams that you can look up and put on copy machine. Let me know if I can help, DAVE SHANK
my 79 3/4 trucks was as per haynes manualnotchiltons)
white: STOP LIGHT SWITCH;
DK GRN: RT RR LAP;
YEL: LT RR LP;
PPL: SIG FLSR;
BRN: HAZ FLSR;
DK BLU: RT FT LP;
LT BLU: LT FT LP;
THIS MAY BE IT OR IT MAY NOT BE. TO BE OR NOT TO BE. THAT AINT THE QUESTION.
FOR TURN SIGNALS, HAZARD FLASHER, HORN ALL IN COLUMN. IT MAY MATTER TO YOU OR NOT, BUT THIS ELIMINATES SEPERATE TURN SIGNALS AND BRAKE LIGHTS CONTROL, I MEAN IF A 3 PRONG TAIL LIGHT IS A BRAKE LIGHT IT WILL ALSO ACT AS A T/S. I WANTED ORANGE T/Ss AND RED BRAKES, BUT IF I DID THIS I WOULD HAVE MY ORANGE LIGHT GO ON WITH THE BRAKES. THE ONLY WAY I COULD FIGURE OUT TO DO IT WAS TO TIE IT IN TO THE FRONT T/S ONLY. I SHOULD KNOW THESE BY NOW, BUT I STILL AINT NO CAR 'LEC-TRICIAN!
