Are the facrtory radio plugs still connected? If they are, get a harness adapter and use it for referance. Here is some info. Use your DMM to test the wire. Check for voltage, ground and also dash lights/dimmer.

+12V DC Battery(Constant)	Lt.GREEN/ purple		Memory	5 amp	Power distribution box
Switched Accessory	Yellow/black		Radio	15 amp	Primary junction block
Ground	Black	Also red
Illumination	Lt.blue/red	Also ORANGE / black
