Hi all. im new here..

I just finished rebuilding a 2004 Neon SXT. It was hit in the front. Not really a bad hit.. did not reach the engine, and air bags didn't explode.

A guy did the body and paint work, and i took care of the mecanical and electrical part myself.
So far, the car is almost finished, and everything is working ok.
I already connected all the cables to the generator, lights, power steering, AC, Radiator Fans,etc etc..

But i got a plug that i can't find where it goes.

So i would need the help of any of you with the same car.
Please... would you just take a look at the wiring harness at the front-passenger side.?
It is the part of the harness that has the plugs for:

1 - Passenger side marker light in the bumper
2 - The window washer reservoir.
3 - Horn
4 - ????????????????????????????????

I can't find where the 4th plug goes connected to.
It has 2 wires. Blue and Black.

May be im missing a part that was destroyed in the crash.

I also have 3 of those air sensors going nowhere that are supposed to be connected to the plastic air box.
I put a high flow air filter and intake instead of buying the much more expensive complete OEM air box at the stealer.
So next to one of these "sensors?", i also have 2 wires hanging but no plug at the end.
The wires are black, and black with yellow, and these are located under the radiator, about the middle of the car.
Would you please also check for these 2 wires?. Where are they supposed to be connected?

Thats all the electrical part left to be done in this car..
I'll keep the car for some time. Looks to be nice.. then i will sell it to make some money out of it.
Thats the idea of rebuilding a car myself it is the first one im doing.

Ok.. thanks a lot .. ill keep reading these forums to learn more stuff.

Good luck.

Axo.
