Good addition, Mike. I quit when I found the first connection...

Ok so as per the wiring diagram, pin 15 on bus A services F25 and G5. But why do I see F25 and G5 on bus B as well, and why does my central warning system still work? But I do have the faint glow issue.

I can't remember if my warning flasher works or not, and will try when I get home.

Also there does not appear to be any non factory wires in there other than the aftermarket alarm, which I have disconnected and plan on removing.

I guess I will have to remove the panel to know more, perhaps there is something hiding behind there waiting for me?

Anyways I better finish what I started first, the X-pipe, then I will get back to this.

Thanks for all of your help

F25 and B5 are coordinate references to guide you to the appropriate page and area of the wiring drawings to find out where the wiring from plug B goes. Each wiring drawing has numbers along the vertical edges and letters across the horizontal. These are the reference coordinates. The terminal numbers with the F25 and G5 reference on plug B are 21 and 15. These terminals run from the 15 buss (only gets power when ignition is in the ON position) to the central warning system terminal 13 and instrument cluster terminal 3 (from plug B21 term) and the warning flasher switch terminal 15 (from plug B15 term.) It takes a while to get the logic of the later drawing reference system but once you do it makes tracing circuits MUCH easier.

Check terminal 21 on the black plug to the central warning system. You should have 12V direct from the battery. Terminal 13 on the black plug to the central warning unit should have 12V when the key is in the RUN position.

Ah, Ok I think I'm starting to get it now.

Ok so here is what has been done. The wire at pin 15 on bus A was burnt, following that up the harness I can see remnants of the original wire (see first post).

There is a red wire that taps into the panel to get power, it then splits to two wire, one goes up to the Hazard switch and the other this wire goes in behind the panel.

The car is original except for an aftermarket alarm, but it does not appear that the alarm taps into the ce pannel at all. So I wonder if it is too blame for the apparent short in that now toasted wire. Maybe the alarm taps into it somewhere farther down the line.

My next steps will be to pull the alarm and trace the wires, pull the ce panel and clean and or fix any damage, and pull my pod to fix a few things and look for anything else funky in there.

I hate it when I have to clean up a bodge repair like you are having to do. One of the first electrical things I had to fix on my '90 was the ground for the DS headlight. Instead of repairing the broken ground wire some a$$hat ran a separate ground to the chassis with the effect of allowing low beam but no hi beam. Glad you've found the patch and can start working on setting things right.

I second that. I just tested pin 15 and it has power? So the short is obviously farther down the harness. Or perhaps it was right where the missing section of wire was?

I peeled back the cover on the harness where the frade copper can be seen. I'm guessing the melted wire most not have gone much farther, if it did I think there would be many other problems.

I originally thought the wire tapping into the panel was for the alarm so I have had it disconnected. I may just leave it disconnected for know, as I don't trust what ever they did.
