66 cutlass convertible, replaces the fuse panel/dash harness last year. Now i looking at the engine harness that plugs into back of fuse panel. one wire is black with white stripe. The other is a fabric/cloth white with small black stripe. These wires along with other unused wires were taped off years ago .Black wire is only about 16 inches long with a connector. None of my wire diagrams show these wires. Trying to clean up some old work. Thanks

heres pic

this is diagram im going off of. i can match every wire except these two

oldcutlass

The cloth one is the resistance wire that goes to the coil + terminal. Black supplies ground to the horn relay from the horn button?

mazey

horn works ok, just actually got it working correctly off steering wheel, for past 31 years i had an auxiiary button under dash. And ive always had her in car too.

mazey

only black white stripe i see is part of brake lite circuit,ut they also work properly

mazey

it has a connector on end and is same length as the wiper motor wiring, is it part of the wipers? Or what else would be near the wiper motor?

oldcutlass

Could be wiper, you have yellow, dark blue, and light blue there?

heres a pic of wiper wiring along the black wire. similiar length.

I'm just guessing but could it be wire for underhood light?

Even a dead clock is right twice a day, unless it is digital.
Do they color it the same as parking lights? I don't have diagram for it.

mazey

possibility. don't see it listed on any diagrams.mine never had on, maybe an option?

oldcutlass

I just got home and looked at mine, a 67. Makes sense, mine does not have an underhood light, so apparently no black wire either.

I've never seen an under hood light on a 66 but then again,I haven't seen all of them either.

I checked my original and the my American auto wire reproduction harness and the black with with stripe goes to the wiper motor. Black wire is not on the 66 wiring diagram, I checked my 67 diagram and the black wire is on it. Must be something to do with the round vs rectangular motor.

oldcutlass

I looked at my windshield wiper motor and the black wire w/white stripe does indeed go to it as a single plug.

mazey

thanks, i removed wiper motor a few years ago, burnt out, (rain-x works great). and bundled all the wiper wiring together. ill figure it out when i get around to replacing motor.

mazey

was surprised i couldnt find listing in diagrams
