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

 

this pic shows the firewall fuse connection, the missing one on left is one im asking about.

 

heres pic

 

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

 

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

 

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.

 

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

 

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?

 

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

 

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

 

here it is

 

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

 

^^^THIS! We have a winner.

 

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.

 

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

 

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.

 

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

 

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.

 

was surprised i couldnt find listing in diagrams
