I am in the process of going through my wiring harness that is removed from the car.  In the area of the radio I have 2 fuse holders. Both appear factory. One is obviously for the radio, but the other one comes out of the main harness and then goes back in. I searched the wiring diagram and I do not see it mentioned. Could it have something to do with the fuel pump? I dont have an electric pump, but I know the wiring is there and has a terminal in the radio area. I am at work, so I can get some pictures tonight. Thanks.

 

 

My hunch is that it may be related to the electric antenna. 

What are the wire colors?

Blue. I found this picture in a folder at work. You can see both fuse holders, I emphasized with black arrows (not very visible). I will get better pics tonight. 

The fuse on the left, as I recall comes out of the harness and goes back in. The other one appears to be for the radio. 

 

 

 

Clean the wires and tell us the wire colors, too.

Looks to me like it is for the rear defroster, if that is where the plug in the bottom right of the picture goes.  The wiring diagram I am using isn't showing the defroster circuit.

I believe this is the thread that helped me when I was reinstalling the OE radio. There were some unused plugs that I couldn't figure out and I think one was blue? Hope it may help you someway.

 

It's hard to tell with the hacking that was done to that harness, but this is my guess.

Steve, thanks. It's all coming back to me. I recall pulling the red wire out of its connector, so I left it attached to the fuse to remind me. It seems there are three fuses back there. I have a 72 radio that has all the connectors. Its not as bad as it looks! Thanks again.
