Well my friends and I just finished dropping in a JDM B16A into a DA. However, when we started it the cars idle was at about 4k. It would not go down. Another question that I had was, how many wires do we need to run for the vtec? Is it 3 or 4?
Its a 93 LS and were using the stock wiring harness and planning on running a p72. What could this idling problem be? I think the car is obd1 and the motor is obd2

2 wires for vtec oil pressure(green plug with 2 wires, one is a GROUND)
1 wires for vtec selenoid(might have a grey plug on it, might just be a bare wire, but either way it's green with a white stripe)

2 total from ECU
1 is grounded.
 
Your car is obd1. Depends on what year car that motor came out of. It could be obd0. Unless its a new one then its probably obd2.
