I'm preparing to install a new radio in my 1990 hatchback. I have a new head unit and new door speakers. There are no dash speakers and the rear speakers are present but untested. The doors have speakers, but are also untested.
I've pulled the amp from behind the radio and have also pulled the amp's 6-connector wiring harness. I'm left with two 8-wire connectors, a black one and a grey one. I'm guessing, grabbing a basic radio installation harness is all I need? Said new harness should connect to the two previously mentioned black and grey connectors and wired to the connectors that came with the radio?
My main questions are:
my electrical troubleshooting manual shows the constant hot wire to the radio harness is light green/yellow, but I'm not getting any signs of life when I probe that wire (piercing the wire, and checking both ends of the connector). The manual shows that the light green/yellow wire goes to the fuse panel and is hot at all times. But, where does it actually connect at the fuse panel? All of the fuses that are supposed to be hot at all times are correctly hot. So, if that is the case, should I expect an open circuit somewhere between the fuse panel and the radio (i.e. cut wire or bad connection) or is there something easier to look for first?
I'm not seeing any signs of life through the switched yellow/black wire when the key is in the on/run position either.
The light green/yellow wire has a 54 next to the wire in the wiring diagram...what does that tell me?
The yellow/black has a 137 next to the wire in the wiring diagram. I believe this wire to be the wire connected to the radio fuse in location #11 in the fuse box.
