There's the big one that goes into the adapter then the head unit, but there is a small one, and we plugged the normal one into the head unit, no dice, but there is a small one that we don't know if it needs wired in some how.

the red wire in that car does not turn off and on with the vehicles ignition due to it having a data turn on for the factory radio you have to get a switched power source for the red wire of the radio i usually wire it to the THICK BROWN wire of the ignition harness behind the knee bolster with a 10 amp fuse on it for saftey

you can pull a switched power line out of your fusebox as well, if you want to. just get in there with a DMM and start turning the key on and off, see what works
