I just got the rear deck speaker system for my 2001 LS. It originally didn't have it. The plug is there, I plugged it in and I get nothing. Am I missing something? I have the Alpine indash premium system. Please help.
Thanks
Here's the wiring....
Stereo Wiring:
According to the FOMOCO wiring diagram for 2000-2002, the factory harness connectors are wired as follows:
The large 20-pin connector:
Position 5 and 6 = right rear (- white and + gray)
Position 12 and 13 = left rear (- whit/violet and + gray/white)
Position 7 and 8 = right front (- white/red and + gray/red)
Position 14 and 15 = left front (- white/black and + gray/black)
Constant power = position 9 (orange.black)
Switched hot in start = position 3 (gray/orange)
Switched hot in run or ACC = position 10 (yellow/green)
Ground = position 16 (black/green)
The 16-pin connector contains the connections to the steering wheel controls and various data bus signals. The cassette systems with external CD changer have a connector dedicated to the signal cable for the changer.
On audiophile systems, there is an 8-pin connector wired as follows:
position 1 = sub + line level signal (gray/red)
position 2 = sub - line level signal (white/red)
position 3 = shield for sub amp signal
position 4 = +12 remote power to sub amp (yellow/red)
position 5 = center channel - line level signal (gray)
position 6 = center channel + line level signal (white)
position 7 = shield for center channel signal
position 8 = +12 remote power to center channel amp (yellow)
The trunk connector (on the drivers side) is number C465 and the sub audio uses these pins:
1 = yellow/red: switched hot
3 = shield for low level audio signal
5 = red: constant power from battery junction box fuse F418 (20 amps)
7 = white/red: low level LEFT audio signal
8 = grey/red: low level RIGHT audio signal
- so troubleshooting you problem -
the trunk connector:
1 = yellow/red: switched hot
5 = red: constant power from battery junction box fuse F418 (20 amps)
so if you get nothing on these it is probably not connected.
On the back of the head unit there is an 8-pin connector:
position 4 = +12 remote power to sub amp (yellow/red) which goes to the pin 1 mentioned above.
