headlight wiring harness
Ok here is the story, I have installed a complete new LL wiring harness on my 65.
Everything works except the headlights.(park light, indicator lights work)
The light switch on the dashboard gets 12v and in the lights-on position sends 12 v via the tan color wire to the fuse box
I also have 12v on the other side of the fuse box in the engine bay 12v
But the lights don't work. If I put 12v directly from another source on the headlights they work.
I unplugging the headlight harness connector in the engine bay from the fuse box.
It appears that the tan connector makes contact with 3 to 4 other connectors (headlight motor wires) somewhere in the harness I guess, this with headlight motors and lights connected to the harness.
When I disconnect the complete harness and remove it from the car the tan wire does not make any contact anymore with the other connecters in the plug.
What is going on? Is this due to bad ground?
Is the harness no good? Headlight motors?
please avdvise,
Ray

The light blue wire from the headlight switch should go to the dimmer on the floor. Then a tan wire (for dim) and a lt green (for brights) should go from the dimmer switch to the firewall connector and then up to the headlights. What voltages to you have on the dimmer switch. The lt blue should be 12v anytime the headlights are on, and the other two depending on whether the dimmer is on bright or dim.

It's hard to tell from your question, if you're working on the headlight motors (to roll the lights over), that isn't done by the headlight pull switch. There is a switch mounted under the dash on the left side that says "headlights" on it. Pulling it toward you rolls the headlights over and pushing it away closes them. Clarify, do your headlights come on but not roll over, or do the lights not come on?

Buckets and lights are in the same harness, when I unplug connector at fire wall and check the ohm on the tan it has one way or another contact with headlight bucket rollover wires.
When I remove harness completely from car the tan does not have contact with any of the others.
I was wonderring the dimmer switch on the floor I installed on top of the silverside from Hushmat?
Thx for your reply when I have time again I will check out what you replied

The only tan wire should go to the dim contacts on the two outside headlights. There's a yellow going to the motor, but not tan. The tan comes from the dimmer, through the left hand firewall connector, and goes to the outside bulbs. (if it's as original) The light green comes from the dimmer and goes through the same connector to all four bulbs for the brights.

I will have to order a new one.
I also checked the voltage on the dimmer switch with light swith in "on" possition.
I do have like you state in your previous reply 12v at Lt blue/black wire and nothing on tan and Lt green/black.
I guess a new dimmer switch will fix the problem.
Thank you for your time and explanations.

Just saw on his other thread, he's ordered one from Ebay.
