sorry guys, i'm about to do a swap next week and i just want to make sure i have everything set straight. i just read about the crank angle sensor and i am a little confuse. I have a 2000 ex(obd2b) and i am swapping in a 97 b18c (obd2a) and i got the conversion harness, do i still have to wire the crank angle sensor ?? i am using the jdm ecu i think, i will have to call steve at HMO back. again i'm a noobie to all of this so please help me out.
