    Their is a 6 pin connector on the back of your stereo. Grab the pink wire which i believe its remote for the stock amp. Then grab your new head unit remote wire and join those two and your set!

    Sweet! That will be useful for the future (I have a 2001 Suburban).
    Thanks for sharing!

    just a thought.... if you guys, or me, or anyone for that matter, are "bypassing" all this factory installed equipment, FUSE EVERYTHING!! if your going to be jumping wires and things like that, its not a bad idea at all.

    i had a guy in the shop, today actually, that tried to bypass a DVD player and completly fried his ignition wire all the way from the radio, to the computer!! lots of smoke, no more radio and about $200 later, he wishes he would have put a fuse on there! so, just wanted to share that info with you guys!

    thank you!!!! i just bought a 2002 tahoe and trying to put my 7" monitor in and i had it all hooked up and now sound. no bose, does have the sub and onstar. i put the stock radio back in hooked up both plugs worked fine, unhooked the small plug no sound. i will try this in the morning, really wanting to get the thing back together to enjoy it this weekend!!!!

    06 Tahoe

    I was wondering if this will work my 06 Tahoe with onstar and steering wheel controls

    it worked perfect in my 02 but i don't have my onstar hooked up anymore and i don't have the wheel controls. you can get they head unit all wired up and just shave the coating off the pink wire and see if it works. also i think you need a module to hook up to make the wheel controls work with an aftermarket head unit, i think but don't hold me to it!!

    Real quick. This needs addressed before someone Fs up their truck. An 02 wiring system is WAY different then an 06. First off, in 02 it was still an analogue setup and the harness kit only cost a whopping 20 bucks. Second in 03 GM introduced the CAN system. It's a form of reduced data they used to help simplify the wiring system, basically, one wire does multiple things using fluctuations in resistance in the ground circuit (DC current travels from the negative terminal of the battery towards the positive ie. "the electron flow theory"). Now in 04 they introduced the CAN-BUS system, same theory, slightly refined for more efficiency. The CAN systems are most obvious in the lock circuits, headlight circuits and radio circuits, the radio circuit varies a HUGE amount from 02 to 06, if you "tap" into some unknown pink wire behind your deck and force feed 14.4volts through it, your playing with fire, you will most likely overload a reduced voltage multiplexed circuit and smoke components not excluded to the radio system.

    Secondly, you do need a module to retain your factory steering controls.

    Iam glad you posted this info....someone was going to really screw something up trying to save a few dollars on a harness.

    The time you spend splicing wires you could have installed the right harness twice.
