Worked on fixing a short for two weeks in tail lights that turned out to be either the green wire to stereo or trailer lights or both. Once I got it all back together I have the flashing OFF for the AHC which was working fine before I disconnected the entire car to find the short. I have...

Thanks for all the help. After countless hours, applying your knowledge, reading the electrical book (a must), learning to use a ohm meter and many conversations with ChatGtp, the lights are working. It appears to have been a combination of the trailer harness and a ground at the green...

Yes, sorry thats what I meant I think. That green/orange wire leaves the fuse block where its plugged in and then to the switch where it becomes green/white.

Also, the brake lights work, its the running lights that are not working. But that wire is connected to the tail fuse, it has continuity anyway

So if i am reading this right, I'm new at this part, the green/orange come from the fuse block and then goes to switch where it becomes the green and white wires to the rear lights. Trying to trace it back from where it plugs in. I have ordered the full wiring book for the 99 LX.

They are in the harness I posted a pic of. It is green wire with orange stripe and blue dots.

Ok further testing and research says this bundle is directly related to illumination. Testing continuity from the tail fuse the large red wire and green/orange wire have continuity on the block side. On the wiring connector side the whit/black wire and red wire have continuity which if I...

Just for kicks I had another headlight switch and swapped them out. Fuse blew immediately. Going to try the jumper wire to relay, just didn't have time tonight.

Ran a quick test this morning with battery connected, fuse out and relay in. Green wire with black stripe had no power. Actually no wire in that bundle had 12v.

Got it. Toyota must have believed a relay would never need anything to put them on the back of that panel.

I can barely get my hand back there to mess with the relay. Of the 4 plugs on the relay, which one is the area to test

Hard to test back where relay is but the fuse has 12v all the time. Ill test one more time without the relay

Foglights not working either but turn signals do

So could the headlight combo switch be bad?

Ok narrowed it down to this connector that plugs in at top of fuse panel next to a yellow connector. I have taken readings on all wires and appears maybe its a black wire with blue dots on it. Disconnected everything i can at main plugs in rear with no change in resistance. May have to pull...
