Ah. I was wondering why I had a fuse spot for cruise but I have no cruise. Thanks! And also, "lumpygrits", thank you. That helped me trace a little bit more and understand what I was looking at with the two wires. There's a charlie foxtrot of wires that it leads into I'll go through to keep tracing once I figure out how to get my little hands in a smaller spot. Thanks for all the advice yall.

Court, You REALLY need to get a copy of the REAL Factory Service Manual(MR252).
It's well worth the cost and so much better than Haynes and the like.

Till you get a MR252, this may help some, even though there are no electrical schematics.

Keep the Haynes in the Jeep and the FSM at home for big stuff.

If it makes you feel any better, I'll be addressing the exact same problem this weekend...although my turn signals are sort of MIA too. I'll let you know what I find and maybe that will help you as well!

Please and thank you! This will probably be my weekend, figuring this out between studying for an anatomy class!

In your case I still say it sounds like a bad turn signal switch, and I think that's what's wrong with mine. I'll try to take some pics to walk you through diagnosing it while I'm working on it.

Before you do anydangthing.
Ign OFF.........
Work the turn signal lever up and down about 50 times and now see is the t'sigs & b'lights are work'n.
Crud on the t'sig contacts will foul them up, quick.

The issue I have is two fold. I know the plugs for the tail lights are badly worn so they don't make great contact. When I plug the turn signal switch in, my passenger brake light stays on, but the turn signal works on that side. The driver rear turn signal works but the front doesn't.
No brake lights at all. Parking lights and headlights function normally with the turn signal switch unplugged.

I recently swapped columns and I know the brake lights worked with the old one, but not the new-to-me one.

Inkeeping with JeepHammer's posts I'd first check and possibly rewire the grounds to the negative side battery terminal. Apparently bad grounds are the primary cause of electrical failures/issues in our old CJ's. Ultimately I went with a grounding bus bar from a breaker panel and mounted it to my firewall near the battieries, ran a 8 gauge wire to the terminal then ran all my ground wires to the bus bar. It's been working great since!

So I figured out what it was today. After tracing wires all yesterday and today nothing was wrong until I got to the back where it goes into my tail lights. Someone who had it before put trailer wires in and when they hooked them in with the brake lights they didn't connect a wire completely. The guy before me said he had the CJ for two years, never had brake lights and he never got to them (he fixed everything else, it has a motor in it with 8k miles on it and a 100k mile no questions asked warranty). Anyway, I took the trailer wires off and threw some sleeves on, crimped, back to how it's supposed to be. Good to go, brakes work!
