I found this wire tucked behind my fuse box today and I don't know what it connects to . Any clues?? It's brown with a
white stripe. (sorry its so small I'm trying to learn how to down size)

 

A little better? I think.

 

i am not sure but is it the wire that goes to the emergency brake peddle to turn on the brake light when pushed?

 

That thing looks somewhat like the end of a fuse holder for some sort of aftermarket gadget like a CB radio. Would be unusual for a wire that short at the fuse box to be factory on any car.

 

I've looked at the emergency brake pedal and can't find anywhere that this would connect, BUT I notice that the light on the cluster does not light up when the brake is set. The wire comes out from the back of the fuse box with many other wires. I pulled back the carpet and the mystery wire looks like it runs towards the driverside of the car.

 

I believe the '68 wiring harness has a brown wire with a fuse for the Rally Pack. Not really sure why you'd have one on the Delmont, however.

 

Does the Rally Pack wire harness have a white stripe on it? Is it possible the harnesses were all the same, I have found power connections for..a electric clock, a map light, and under dash courtesy lights that did not come on this car. The connector on the end of this wire looks like a stiffer wire would be plugged into it. (It has a hole in the center of hard plastic)

 

Okay, I must be dense but how could the wire be running to the driver's side if the end you are holding in the photo is connected to the fuse block? Does the end in the photo appear to be some sort of socket or connector when looking down into it?

 

The end of the wire I'm holding goes behind the fuse box at the top. The wire that runs towards the driverside comes out of the bottom of the fuse box. If you can enlarge my picture you can see it running out the bottom.

 

The e-brake pedal should have a pin switch screwed into the top of it. It looks pretty much like a door jamb switch and is designed to make contact when the pedal is pushed. There is a single wire with a bullet connector that attaches to the pin switch. It looks like what you have in your hand.

 

Could this be the point of contact. I've looked all around the brake pedal and this looks like it could be it BUT It seems that I'm missing a piece.

 

Yep, you are missing the switch part that mounts in that silver bracket.
Grounding that brown wire should make the brake light glow when the IGN is on (providing the bulb is still good...)

 

Thanks Lady72NRob71, Joe, 68Tom, Texascarnut, Jensen Racing 77, for your help in solving this mystery. Lady72NRob71 I know the light on the dash works cause when I first got the car it was low on brake fluid (Thats the only thing I didnt check!!) and when I drove it to it's first show, The pedal went to the floor on the way home. There nothing scarier then having your pedal go to the floor and a red idiot light come on at the same time. So now I guess I have a new piece to hunt down, It should be fairly easy to find this one. The last part of my vacation will be in Ohio and I know of a yard that has a couple of 68 98's and a 4 door Delmont. Thanks again everyone

 

I had a heck of a time finding one for my 65 Cutlass. Finally contacted these guys.

Finding what, an ebrake switch? They are used on just about every GM car and truck with a foot pedal ebrake.

 

This was one of GM's widely-used interchangable parts.
