Re: 68 f100 signal lights

fixed em, not sure how. there is short somewhere under the dash. havnt located it yet.

odd thing is the rear light, when the blinker is on, are revered. left is right right is left. in front they are correct. i didnt touch the wireing. i assume it was like this when i bought it.

any ideas where the wires would be crossed. i assume somewhere after they branch off heading to the rear.

crazy never seen this before.

Re: 68 f100 signal lights

I have seen that before, but cant remember the actual cause. First I would check and make sure someone hasnt whacked into the rear lights for a trailer plug, if so disconnect it and test. Other wise,
1. someone replaced t/s and got the rears crossed putting them in connector.
2. someone has cut/spliced the harness going to the rears and gotten the 2 wires 'crossed'.

There shouldnt be more than 5 wires or possibly just 4. Left signal. Right signal. running(tail/parking lights). reverse light. and maybe 1 for tag/clearance lights, altho usually those are all tied into the tail lights.... This is the harness for the REAR of the truck.
