I might be mistaken, but when i installed my head deck the wires all had writing on them. Ant, grd, f-l, f-r and stuff like that. Not totally sure though. I will check at home to see if i still have a copy of the schematic. sometimes you can go to jeep and download a wiring diagram or the pioneer website should also have wiring diagrams. Most wiring will be the same. Blue is antenna. thats all i remember. good luck
