I searched, found nothing that helped.

This is the problem, After relocating my battery to my trunk, installing nitrous and removing my cruise control module, my passenger headlight is dim, the horn does not work, my airbag light stays on and the high beam indicator says on after turning high beams off.

I check the harness that is pinned between the washer bottle and the frame, no corrosion or grounding out there. I checked the harness going under the car to the passenger side for the headlight and horn, no problems there. I plugged the cruise control module back in and turned on the lights and it was still dim. I also checked the fuses in the fuse box, none of them are blown.

I do have a code that i cant seem to trace the source to, it is Brake Lamp Circuit Open or something, checked the harness on the trunk to the tails and that also seems fine.

So i basically am stumped here, i can not figure out what the problem is.. I have the old battery grounds grounded to the tray's location against bare metal.. the battery itself is grounded in the spare tire well, all the nitrous wiring seems solid.

Could the problem be solved by putting an inline fuse from the battery + connection in the engine compartment to the red wire in the passenger headlight?

Any ideas?

Thanks

Thats an odd problem, if it happened only after the battery relocate, I would check that ALL of your grounds up front are good, that the battery ground is sufficient, and the ground for the headlight is good first, then go from there.
