I want to say thanks for reading all this and helping out! So I am helping my friend with an 83 Z28 to work out all the seemingly small issues.
First we came across the first problem when trying to install a CD player where there was
since he bought it. Wired it all up using Haynes manual wiring diagram and nothing. I whip out the voltometer and see that neither the constant power wire (yellow) or the ACC power (orange) are getting power across them. I check out the radio fuse, fine. The fuse that is connected to the orange wire is a 30A fuse that controls whether the interior lights come on, which has been blown since hes had the car and continuously blows immediately anytime its replaced. I came to the conclusion that they are connected because I can stick one lead in the fuse holder for that fuse and touch the orange wire and get a continuity signal, unless they are both grounded at that point for some reason?
I found a wire jammed in the ECM fuse and it leads to a wiring harness that is also tapped off the two brake signal wires and the other end connects to the turn signal lever in the steering column
and also through the firewall to a box labeled only with a serial number and description for adjustment screws to include: low speed adj, sens adj and cent adj. It also says somethin about transmission selection. The box is mounted by the horn on the drivers side fender. Once on this side of the firewall wires split up and some disappear behind the engine. Also from this box comes a throttle cable going to the throttle body. It also reads "DANA Corp.", the only reference I can find to DANA and camaros is a dealership called DANA that made performance 1st gen camaros, somewhat comparable to what Shelby did to mustangs. By the box there is 2 plugs just laying there that trace back to under the steering column on the engine bay side of the firewall. One is just a ground wire, no idea what the other one is, any ideas?
It seems as though this box is something that is supposed to be there from the factory but the wiring is quite obviously aftermarket. This is the first time that I have worked on an older car so forgive my ignorance.
It all comes down to; any idea why this 30A fuse is blowing and why it controls the interior lights when the manual says its the ACC power wire? What is this seemingly OEM box that has quite obviously aftermarket wiring involved? what are the 2 plugs just hanging around supposed to be connected to?
