Electrical Issues

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...

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.

Well the thing in the bottom pic looks like it may be the PCV breather line that might lead to the air cleaner for the carb. In the top two pics you can see the grommet on the valve cover, that's missing something.

As far as the connector goes, I don't think that has anything to do with your headlights.
It looks like it may be some kind of emissions connector.

You live in a corrosive environment, & the light problem may be the bulkhead connector needs to be taken apart & cleaned. If you do this, be sure to disconnect the battery & put some dielectric grease on all the bulkhead connector's terminals after you get them clean.

There was recently a write-up in JP magazine on this.
Here is a link to their website;
Jp Community, Forums, & Blogs at Jp Magazine

That link might take you to their forums, look for a link there, to the JP mag's homepage.
There do a search for that article.

I did a little more troubleshooting to try and figure out what was going on. It turns out that the yahoo who installed the aftermarket lights just wrapped the hot line around one of the existing fuses. I also found a blown fuse even though they were all intact as of a couple days ago I'd forgotten to check them earlier.

I replaced the fuse and now I have the parking lights back, the tail lights (which hadn't been working) are working, the brake lights are not working and the turn signals are not working, both of which HAD been working before.

The sockets for the side indicator lights have been exposed so I checked them for power before I put in the bulbs and lights that I have and BOTH of them are sparking and blew the new fuse I just installed.

I am getting no power at all to either of the headlights.

I do have power to all the tabs in the switch and I've obviously disconnected the after market lights until I get it sorted.

Any idea where I should go next?

Just an update... the turn signals are working and the headlights are working so I'm down to just dealing with the brake lights and I'm suspicious of the actual switch on top of the brake pedal. The brake light are intermittent and the thing looks like crap so I'll source a new one and replace it and see what that gets me. At least I'm getting power to all four corners now.
