Question about headlight switch

[one3n3my]

I have the Painless Performance Wiring Harness P/N #10206 and having issues with my brake lights. There is no actual fuse for the tail lights and I have installed new brake light housings for both right and left. Would the headlight switch actually cause the tail lights not to work? Mind you the headlights, turn signals, and brake light does work.

Just lost in where the issue is lying.

The headlight switch can be the source of tail lights not working.

Well you do have a fuse in the fuse panel for the tail lights. It's labeled Tail/stop dome. Look at the picture.



The head light switch feeds power to the tail lights but not the brakes. If your fuse is blown you won't have brake lights or dome lights.

You say you have issues with your brake lights, then you say they work. Did you mean issues with the tail lights?

The picture posted is for the pre 68 trucks the 68 and newer trucks use this one.



There is a plug in the firewall just behind the distributor that carries all the rear light wires. The brown wire is the tail light wire. Check it for power when the HL switch is on.

If you want to test the tail lights, and the headlight switch, you could pull the headlight harness plug off the switch and jump between the red power wire, and the brown tail light wire. If they don't work then there is a problem with the brown wire to the rear lights.

If the lights work, then jump between the orange wire and the brown tail light wire. The orange wire is actually the feed wire for the tail lights. If the
tail lights work then the headlight switch is bad.

Here's the manual for the harness PN 10206, It doesn't show the new style fuse panel as a standard part or an option. Did yours come with it or did you order it as an option. I'm hoping he'll come back with more details.

Do you have the newer HL switch?

It came with it. If you look up the part # on there web site it has it in the photo. just a little bigger then the original so you have to cut the wall about 3/4" for it to fit. other then that seems to be all there. I had a few issues as I am running the original 250 inline 6. but seems straight forward. would like to also know what he finds.

I have the newer fuse box. The install was pretty straight forward for everything to work. The headlight switch is the original one. I am going to try and put a new switch in to see if that clears up the issue.
