underhood wire harness extension
« on: March 11, 2011, 08:56:08 PM »
Coming off the fusebox I have on my 67 camaro a extension for the headlight harness that attaches to the fender under the hood hinge, it plugs into the fuse box outlet and then into the light harness and is about 6 inches long or so.I am trying to get a new one but nobody knows nothing about it.Anyone here have this on their car?

Brake differencial warning switch connection?  What color is it?  Do you have a picture? A tan wire would correct for the switch.

Yep. That's for the "differential pressure warning switch" located on the distribution block attached to the master cylinder.

I don't think he's talking about just the tan wire but the whole plug in set up.  I've never seen that, but I don't have much experience with all the variables.

We've talked about this ext before and no one seems to have an answer . Its not the head light harness its an ext for the engine harness. I've got one too. Have found two of them in LA cars . Head light harnesses don't have that brake switch wire in them only the engine harness has it

Ah, gotcha. No, I've never seen one like that either, but there were sooooo many dependancies for the harnesses that it's impossible to say. You'll probably just have to purchase a new engine wiring harness from one of the local repop houses.

well its just that the one in the pic is butcherd up so bad I would like a new one.There must be a reason for GM to have put that extension on there.I know its hard to get at once all the brake equipment is in place.I would have thought that factory fit would have this item they dont list it in the catalog.By the way I also have this on my norwood build 67 Z28 also so its not just the LA cars that have this and my other car isnt a RS so its not RS related either

Ah.  OK.  Very interesting...  I guess if you wanted to put one back in after buying a reproduction harness, one could buy the parts and do it themselves.  But that would involve cutting into a new harness or getting a bunch of wire. 

I wonder how/why the tan wire isn't duplicated in the engine and extention harness.?.?  Meaning, if the extention was just added, there would be two tan wires.  Maybe THAT is why it was added??? 

Ah, the mysteries of this hobby!

UPDATE: I just talked to Don Donovan of factory fit and they now know what I was trying to describe to them.They do NOT list this in their catalog but they do have it and if anyone needs one give him a call. He said it only came on california built camaros with power brakes.I told him my norwood 67Z also had one so maybe its for cars with power disc or drum brakes.Anyhow they now know of the extension so they can get whoever needs one a extension. ;D
