AvicD3Silverado87

No I couldn't find it. So I just tap into wire tha goes to the head lights?

I got the D3 in and working but there are two problems: 1.The screen does not dim when the head lights are on. What wire has to be hooked to the GMOS-04. 2.There is a high pitch hiss coming from the speakers that goes with the rpm's and I checked the ground and i think its a good ground. Any suggestions?

Thanks alot, I hope I can get this installed tonight I will post some pics when its done.

I'm installing a D3 in my 04 Silverado w/ Bose I need to know where the VSS and the reverse wires are. I also was wondering if I could use the stock XM antenna. Hope that some can help.
