i have a 93 ex and i have put a 01 gsr motor in it. does the obd2 wire harness inside the car match up with everything. if so why do you have to add IAB, knock sensor shouldn't the wire harness already have these wires
 
You need to do some research before you start your project.

Might I suggest starting here at HS, there is a TON of information about this and it's been covered more than one time.

Then make your way over to hybridgarage and check out the archives.
