best thing and one of the hardest is to stop listening to your cousin, he does not know as much as he thinks he does, then PM Lenko and thank him for taking the time to set this up in the Frequently Asked Car Audio Questions sticky at the top of this forum
I would like to thank John Lenko for the wiring colors and polarities.
Radio Wiring
Off the radio harness:
Left front +: Tan wire, pin A8 (to E2 on amplifier)
Left front -: Gray, pin A9 (E3)
Right front +: Light Green, pin B11 (F1)
Right front -: Dark Green, pin B10 (E1)
Left rear +: Brown, pin B8 (E6)
Left rear -: Yellow, pin B9 (E7)
Right rear +: Dark Blue, pin A11 (E5)
Right rear -: Light Blue, pin A10 (E4)
On the amplifier harness:
(inputs are as noted above), outputs:
Left front tweeter +: Black wire, pin E13
Left front tweeter -: Yellow, pin E14
Left front speaker +: Dark blue, pin E15
Left front tweeter -: Light blue, pin E16
Right front tweeter +: Light green, pin F2
Right front tweeter -: Purple, pin F3
Right front speaker +: Orange, pin F7
Right front speaker -: Dark green, pin F6
Left rear tweeter +: Tan, pin F15
Left rear tweeter -: White, pin F16
Left rear subwoofer +: Dark blue/white, pin F5
Left rear subwoofer -: Light green/black, pin F4
Right rear tweeter +: Red, pin F14
Right rear tweeter -: Tan, pin F13
Right rear subwoofer +: Light blue/black, pin F11
Right rear subwoofer -: Dark green, pin F10
Note that that includes RPO radio code U85.. which is the Monsoon radio I think.. so.. if you don't have that.. you won't see ALL those wires on the amplifier.. you'll just have wires from the radio straight to the speakers (esp. in the front)... sure fire way to check - look at the colours of the wires to the speakers themselves.
PM Lanman for this
Radio 12v orange + radio harness
Radio Ground black - radio harness
Radio Ignition (Class 2 Serial Data)
Radio Illumination gray (dimmer) + radio harness
Factory Amp Turn-on pink + radio harness or amplifier
LF Speaker +/- tan - gray +,- radio harness
RF Speaker +/- lt. green - dk. green +,- radio harness
LR Speaker +/- brown - yellow +,- radio harness
RR Speaker +/- dk. blue - lt. blue +,- radio harness
and Mark65 wrote that the wiring is as such
Radio 12v - orange
Radio Ground - black/white
Radio Ignition - SEE NOTE
Radio Illumination - brown/white (dimmer)
LF Speaker + - tan
LF Speaker - - gray
RF Speaker + - light green
RF Speaker - - green
LR Speaker + - brown

NOTE: There is no accessory wire in the factory radio harness. You will need to get this from another location. I recommend going straight to the ignition switch. Its the 12ga orange wire...be sure to use a 5 amp fuse if you splice into this wire.
And since no one knows what year car you have you will need to search anyways
