My brother got in an accident with his Z...he hit a boulder on the road in the mountains and it tore off the front corner of his front bumper, tore off all the plastic shielding, damaged the radiator core, ripped off the wiring harness from the headlamp and cracked the front rim. We had all the shielding, radiator core, the front bumper, and the rim replaced; however, the wiring harness that plugs into the front right head lamp and two more other plugs got torn out and the only way to replace them is to get a whole new engine wiring harness and labor, which i got quoted between $1300 to $1600 from 4 different places, including the dealer. One body shop said that Nissan doesnt sell the plugs seperately so your better off splicing and soldering the wires. We did it for the headlamp and that works fine. We were able to salvage the wiring for the washer reservoir and that works fine too. However, we found two more plugs that we cannot find where they plug into. Does anyone know what im talking about or have a 03's 350z base engine wiring harness diagram so we can figure out where they plug into? on plug looks like a bulb went there but all the bulbs in the headlamp are fine and working. The other one is just two wires without a plug at all. Any help would be awesome.

 

My '06 has a couple of unused plugs in the RF corner. They're not connected to anything.
