I bought a lemon off offer up. The CEM is bad and It looks like the previous owner also tampered with the headlights. I bought a refurbished CEM off EBay and the passenger side headlight still doesn't work. I wanted to know if there are any videos or diagrams on how to route the passenger side headlight with the drivers side headlight or directly to the battery. All tips/suggestions are welcome. Thanks

 

the right way to do this is to get access to a wiring diagram (Haynes manuals and other sources should have one) and set the wiring back to stock. Then test connectivity from the switch to the CEM and from the CEM to the headlight socket for both left and right sides. When you say the passenger headlight doesn't work - is that for just the low beam (which has a relay in the CEM) or the high beam (which is on a separate relay/fuse path) or both?

I'd probably start by checking voltage and ground at the socket and see if there's any signs of heat damage (cracks in the socket, bubbles on the wire insulation, corrosion etc.) Possible failure points would be fuses/relays, headlight switch, multi-function stalk, wiring/wire junction points, CEM/CEM connectors, headlight socket and wiring connector at the bulb. Oh and double check the bulbs (lol, I did that once...)

 

The low beam and high beam don't work on the passenger side. I don't want to buy another CEM because I've already put too much money in the car to fix other issues. Is there a safe way to connect the line directly to the battery? I've been looking for videos, but I only see tutorials on how to do it to motor cycles.

 

well if both the low and high beams fail on one side, then that rules out the CEM as a suspect since the CEM is not in the high beam circuit path. with both high and low out on one side, I'd look closely at the wiring/socket around the passenger side head light bucket itself - check for a proper ground etc.

 

I sent the CEM to xemodex for diagnostics and they told me that the light didn't work because of the CEM...
I unscrewed the headlight panel next to the steering wheel and I can tell it's been tampered with. My neighbor checked the grounds and said that wasn't it. I think it would be easier and cheaper if I could find tutorial on how to make closed circuit headlight safely.

 

Modifying the circuit sounds like a pretty suspect idea - if you DO find a video, it's going to start with the premise the lights are working. If you start with the lights not working and make a bunch MORE changes, you might end up with more problems than you have now (in fact, I'd bet on it). If your CEM has been diagnosed as bad, have you done anything to correct that? Seems like you'll be wasting your time until that happens.
