So i cant really figure out wtf is up with my cars electrical system since i relocated my battery to my trunk and installed my nitrous system. i checked a problem spot mentioned in another thread, the harness between the washer bottle and frame, and that was fine. i didnt check the headlight grounds yet or the relay for them

so let me state the problem since i relocated my battery and installed n2o. the passenger headlight is dim, the horn does not work anymore, the airbag light is constantly on and the high beam indicator stays on after turning the high beam off. the passenger headlight just looks like it is not getting enough power..

also, i cant seem to figure out why the nitrous system works for a while, then wont work until i plug the mini fuse tap into a different spot. i have the purge, bottle warmer and main system soldered into one tap, works for a while then i have to draw power from a different fuse spot and the previous fuse spot still works after putting the original fuse back in.. IE i put the rear defroster fuse back in and the defroster still works but the nitrous system will no longer have power..

while i was tuning, my service light came on.. i think this one did it.. [Restraint] B0035 ADS closed/shorted to ground and i have had this one on for a while [Brake] C1295 Brake Lamp Switch Circuit Open. My DRL disable ground is still solid so that isnt triggering the service light..

so i am completely out of ideas other than taking it in..

any help is appreciated,

thanks

as far as the headlights go sounds like drl might be chasing a ground. could be all related. try back probing a direct ground to ur headlight n see what happens. hope this helps
