Ok got a question. Installing a Bluetooth radio in my ‘94 gmc sierra k1500. I have this wire that I disconnect from the tuner part. It the white and dark green wires with the small clips. What is the dark green wire cause there is no spot on the aftermarket plugs for it

most times either attached to the backside of the radio or somewhere close by behind the stereo in the dash

go to walmart or bestbuy and get the wiring adapter so you dont have to cut any wires. they are color coded

look under the dash.

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

The only way to get this is from a Salvaged Truck. I Still have my cd Player in My 95' Silverado because I could not find one Either. I went ahead and Installed the Aftermarket System and just unhooked it.

make sure piston is pushed all the way into caliper. if it is install without shims
