I need some help to find out where all the harness grounds are, in the engine bay and inside under the dash. I have a dim passenger side headlight, and can't seem to find a "problem ground". I think I might be missing one or two somewhere...

Next Question:
Being a 1995 2 door, it's a bit of a "one of a kind" as it was the first year for the 16v in a 2 door, and then the next year they were OBDII.
If I can't track down my problems, I will likely swap the harness. Were the vehicle harnesses the same among all 2 doors with different engine harnesses, or am I limited to finding a 1995 only?

I had the same dim headlight on my samurai, it turned out to be one of the termianls on the headlight plug itself had almost pushed out the back. I pushed it back in and bent the tab a little more so it wouldnt happen again, even though I looked at it a couple times and spent a couple hours with  a DMM trying to figure it out turns out I dint look good enough. some times its the simple things. Another way is to plug the 2 + wires( in the harness for the headlights) up the the headlight and run the ground straight to the - terminal on the battery just to see where the problem lies
