Auto headlight upgrade.

OK so i searched found some info, now for my questions I got the sensor got the auto headlight switch put everything in and my auto headlights do not work I have all the pins behind the auto headlight are filled up only 3 is left blank. What now is there something I missed a relay? could the sensor be bad? Need some advise as what to check.

I remember when I bought my old ZJ, the guy said that he thought the relay was going out and that's why the headlight was wonky.

Let me know if you get this up and running! I'd love to finish my upgrade

could the auto switch not be working?it works fine to turn the headlights on and off it just does nothing in the auto section. I cannot find that junction box anywhere i have relays under the hood and behind the glove box thats all i can find.

I just did this in my 95. All I needed to install was the blue sensor under the defroster grille, the auto headlamp switch and the auto headlamp module...that last item goes just to the left of the relay block under the glove box. It's a tight squeeze to get it in there but I was able to install it without taking the dash apart...only thing is I was only able to secure it with one mounting screw instead of two but I haven't had any issues. Let me know if you need me to take a picture of the module for you. It won't be until tomorrow (Wednesday) nightbefore I can tthough. If you can't find any modules I might be able to dig some up from the local junkyards when I get home next week. There are quite a few with auto headlights in them.

Sweet can you take a pic for me I'm sure this module is what's causing my issues. Don't worry about going to the junk yard I'll have to pay shipping and duty on probably a cheap part lol

Sweet thanks man my jeep is in pieces lol my dash is laying all over the interior I guess since it's on the passenger side I can put my dash back together or should I wait. Also what could I do to make it easier to get to that spot where the module is?
