Yeah previous owner was a bright one, I found lots of duct tape

 

Ok, so I am going to correct myself... The module (relay) that you are looking at is actually the headlight delay module. The headlights do not appear to use a relay system. That module is for when your headlights and you turn the truck off, and then turn the switch to lights off. It allows the headlights to stay on for a few seconds.

At least that is what the electrical diagrams state (and i know from my jeep that this is the case)

So, technically (if everything is wired correctly) you don't need that switch because it runs separately from the head light switch

It may be that the delay module is broken causing things to short circuit or maybe that the headlights are wired incorrectly

Like your original post stated: wiring nightmare

I have ALOT of that going on with my jeep but luckily if I can't fix it, I have 4 people that i work with that are also experienced electrical techs

 

Your awesome, So what is the LPHD/ DLY Fuse?

I got another one of those modules from a 90 Jeep I snatched at the junk yard So Im gonna rewire everything and try this new one too

 

A 12V constant that provides the power to your headlights when it is in the "delay power off" mode

 

So can I bypass this?

 

from what the diagram looks like you should be able to just unplug it...

 

Ok, Im just getting over the flu so Im sick as hell still but I hobbled myself outside and rewired that whole plug, New ground, jumper wire gone and rewired into harness, duct tape gone and all 4 connections redone with butt connectors and shrink tubing. Trying both modules I have I have no lights still, Next step headlight switch? I ordered one in at work, Gonna go get it tomorrow. Any other suggestions on why all the lights would go?

 

Ok I got anxious and drove down to the local service station cause I knew they had a Cherokee I got the other module from and grabbed a headlight switch, It was already out so who knows it might be dead too, But swapped it in, still no lights, Anyone? I just need lights back this is my daily driver

 

I got a vehicle to borrow to get to work today, Getting the new headlight switch to be safe, checked fuses. Does anyone else have any suggestions on what would make all my lights go (even dash lights). Thanks as always

 

Are the dimmer switch wires intact?

 

I know when you pull back on the switch, the blue light in the dash wont even come on

::EDIT:: Found the dimmer switch wires look good

 

Wondered if they were cut, or switch was bad, causing loss of continuity?

 

Anyway to bypass it, just to see, I dont have a test light here, Any fusable links or anything else that could just pop all of a sudden while driving and loose everything.

According to the wiring diagram there is a fusable link on the hot wire coming into the headlight switch. I cant seem to find it, I did notice the plug going into the headlight switch has been replaced, as there is butt connectors on all the wires except the main thick hot wire

 

Im loosing hope, and I know its gotta be something simple

 

I would think it is that the headlight switch is not geting power - i can't see it being anything else (as NO lights are working)

Sorry I haven't been more active with the electrical issue but it is flooding right now (why do people live in North Dakota!!) - by the way, if anyone wants to come help with sandbagging-I am sure I could find room at my mother-in-laws house
