Well, when I got the Jeep the headlights didn't work but the parking lights did and the brake lights did and the turn signals did. The guy I bought it from swore it was a switch issue and ordered a new switch and mounted the lame little front lights to see me through. I was never really convinced that was the problem but sort of went along with it.
Last night I fired up the Jeep to go home and NONE of the lights worked. Not the old ones or the new ones so I left the poor thing alone in the parking lot and went to get it today figuring it was a ground issue that I could sort out.
I busted out the test light to make sure I was getting power to both the old switch and the new switch figuring I could just bypass the old switch if I was feeling wild and, as it turns out I do have power to both. Now, I can't find where everything is grounded but opened the hood to trace out the wires and see if anything jumped out at me. Oh yes... I see an issue...
Also, if you look in the background you will see this:
And since I found this sitting loose in the engine compartment, I'm guessing that's what fell off, but I can't seem to figure out what the rectangular end goes to.
What the heck is the thing in the first picture and can I just splice everything over?
A way to reconnect the line in the third picture would be a nice bonus if anyone happens to know where it came from.
