Question about 1994 GMC Jimmy

1 Answer

Car stereo wiring

I'm trying to put an after-market head unit into a 94 GMC Jimmy. The previous owner cut the car's original wiring harness plug off, so I can't buy a wiring harness that i can plug into it and match up to the car stereo. Can anyone tell me what color wires go to what? This is driving me nuts.

If your original harness is still hanging out of the dashboard I would just opt for the $15 aftermarket cord. Then it's just pretty much color code wires together

I have a 91 honda accord and the previous owners cut the nuetral safety switch wire off underneath the dash. where can i get the wires to replace them?


  1. Try your local junk yard or buy it threw the dealer, the plug can be replaced, most likely he cut it at the switch and not at the connector plug on the harness.

Installing an aftermarket stereo, spliced the wires and have everything connected including the remote wire to the factory amp wire but still no sound.


There is no remote wire on these newer trucks....03 and up....u have to buy the harness....although i didnt....i have an 03 gmc sierra and just pulled the schematic and matched the wires. And there is no programming to do on an aftermarket stereo.....I work for GMC and we cant program aftermarket stereos......if u buy the right harness ...and its over $100 then everything should work just fine.....and this does not disarm ur alarm system either....mine still works fine....hope this helps

99 gmc jimmy sle keyless remote and security issue


Hi: From my experience the security issue is easily solved because hitting the factory key FOB lock button is the only way to activate it, hitting door lock button will not activate it. When installing a remote starter no wires are cut usually, just spliced into which means... make sure that where wires were spliced they are taped. If you have the original factory key FOB use a quarter and pop apart, replace the battery, key FOB should have retained its factory setting if your lucky, if doesn't work go to internet search and find programming procedure. Hope this helps... please rate suggestion...ty
