i am tryin to wire up my alpine 7998 in my c5 vert. which color wires on the factory harness do i tap into. i have the adaptor so i dont have to cut the factroy harness. i have a yellow 12v power,blue power antenna, black ground, red for the ignition on the alpine harness. which colors on the factory harness do these wires go to. itried a few different ways and nothin worked. i dont wanna hack anymore wires till i know which ones to connect too :confused: :confused: :confused:
The harness should have come with a little list of what wire goes to what. All you really need is +12V, ignition, power antenna, and ground, since you won't be powering th speakers from that head unit.
The adapter worked for me except the switched wire. Apparently the Bose system is turned on by the computer and not a switched power wire. It's just a blank spot in the stock system.
It sounds like you only have the adaptor that came with your alpine deck.
You also should have had to buy a seperate ($15) adaptor for a GM (1997-2002) vehicle (corvette). If you only have the one that came with your deck and the stock harness from your stock deck you are missing another adaptor the ($15) one for GM.
