Hi, can someone tell me what each wire for the harness is for? I got a aiwa headunit andi have 1 wire to power (acc), 1 to batt direct (backup) fuse 15a, 1to ground, 1 to relay control to power antenna/to remote control fuse .5a. and 4 pairs of speaker wires. I'd like to know what the stock wires for the harness are for. Thanks
