ok well my car had a little trouble,we had a big flood and someone messed with my alarm remote and tried to start the car with the engine submerged and they messed up the computer,so the mechanics here couldnt get the computer for my engine so they put in the d15b engine and the d15 computer but with my stock wiring harness,and now none of my a/c buttons work,my dash doesnt work properly,when doors open no lights come on,only trafficator lights work and the car drives really weak.

anyone know where i can get a d15b wiring harness to buy,i really am beggin for ur help guys.
