Did the 91's come with a radio wiring harness/plug pre-installed? If so, where'd they hide it?

If not, can I just snip the lighter socket wire and power with that. Shouldn't draw that much juice (?!?!)

TIA,

Seth

If the plug is gone, your gonna have to test for wires. All GM cars are the same, and are as followed.

Orange- 12v constant
Yellow - 12v switched
Black - Ground

Front left speaker + tan
Front left speaker - gray
Front right speaker + light green
Front right speaker - dark green

Rear left speaker + brown
Rear left speaker - yellow
Rear right speaker + dark blue
Rear right speaker - light blue

Alot of times when the plug is cut off and you have to hard wire the radio in, some of the fuses are cooked and you wont read any power. Make sure you test ALL OF THE FUSES if for some reason you cant find constant power or switched power.

Thanks.

Any reason the constant power has to wire direct to the battery like the install manual says? Can I just drag it from the fuse block?

The power wire that went to the factory radio is enough power to run just about any radio out there today, unless you have one of the 60x4 Alpine decks. If thats the case, run the wire straight to the battery, or grab power off the large gauge red wire at the steering column.
