Ok well my friends and i have been working with the wiring on this CA for about 3 days and we cant get the god damn thing to run. I am almost done with this project and ready to give up. If anyone can help let me know. I am in the Nashville, TN area if anyone is local and can stop in and maybe point something out that we are over looking.

Its the big *** round sensor thing on the front of the motor with the little mitsubishi symbol on it. Take the bolts off and pull it out carefully. It might have alot of **** on it and just need to be cleaned or the end piece could actually be chipped/broken off.

Well there was nothing wrong with the CAS so I dont know what to do. Its getting fuel up to the fuel rail and its sparking, but the fuel is not going through the injectors. I need help now.... I want to drive this mother ****er!!!

Yes, you need it. Its a silver box about 4 to 5 inches long and an inch wide.

Well I got the resistor box and hooked it up and the same thing is happening... When I got my harness is was hacked all up so i guess its just going to take a LOT of time and patience... I still have wires that i dont know if they need to be hooked up or not... Like I have a solid blue one that just comes out of the middle of the harness... WHere the hell does that go? Thanks for all the help

Ok... In the first picture there are 2 plugs that come from the CA harness towards the battery. The one on the left has a solid white and solid black wire. The one on the left has a blue/white stripe and solid black.

In the second picture there is a single wire that just comes out of the middle of the harness. The MAF sensor wires and wires that run to the resistor box are in the same harness. The single wire is solid blue.
