1967 RS mystery inline fuse.

On my 67 rs Ive got an inline fuse holder that is located right by where the relay board for the headlights is, under the drivers fender. Its a fairly long plastic white fuse holder with a black plastic mate. Its a black wire. Its never had a fuse in it since Ive owned the car. It looks like its part of the factory harness. Any ideas what this might be for? I have factory a/c if that means anything. 327 pg originally.

Re: 1967 RS mystery inline fuse.

Is it taped in with other wires in the harness or taped in a few spots ?.

Can you tell what each end of the fuse goes to ?.

I wonder if it might have been for a mercury underhood light or for a high speed relay for the blower motor.

Someone might have added it at some point for something unknown and you may want to trace down the wiring.

Re: 1967 RS mystery inline fuse.

It looks like its factory but I guess its possible that its not. I never tracked it down as it disappears inside the fender and under the rad support. I guess I will have to. I thought someone might know off the top of their head what it was. Its not that shiny soft plastic that many aftermarket fuse holders are. Its a harder plastic and a decent gauge wire.

Re: 1967 RS mystery inline fuse.

OK, so I just checked the aim and page 179 seems to show the fuse holder at the very bottom of the page. It comes from the horn relay and goes through the bulkhead connector. It comes out and joins with other wires and eventually goes to the red wire on the ignition switch which I believe supplies 12v to the coil in the run position. This all seems very strange to me. Its as if its supplying 12v to the horn relay in the run position but theres already another wire supplying 12v to this very same point on the relay.

Sounds like once upon a time your vehicle had an alarm ignition intercept.

Im beginning to think that too. I will have to try and track it down on the car tomorrow. Was that type of thing ever a factory option?

No alarms were offered - Only aftermarket had alarm systems for install.

Re: 1967 RS mystery inline fuse.

So, I checked it out today. It goes from the bus bar on the horn relay, the fuse holder is right under where the rs relay boar is and then it hoes through the fender well area with the rest of the harness, and then it, get this, ends. It just hangs down to the subframe onder the brake booster. I guess it was just a leftover wire from something that someone installed back in the day, pre-1980. Maybe it once went through the firewall for something like a cb radio or something. I will be removing it.

Re: 1967 RS mystery inline fuse.

I'm willing to bet at one time there was a barrel key switch mounted on your fender or under the dash for the activation of the intercept and or alarm. I have an intercept in my z that is a combination ignition intercept and cable hood lock. I assume by your description there was an alarm box and maybe horn mounted on the fender wall to finish the system that took power from the bus-bar.

This sounds feasible. I remember seeing that key in the fender deal on other cars back in the day.
