Re: Check Engine light right after swap (VTECVillain)
i got a cel codes 10 14 15 20 21 22. I think I messed up on the wiring. I have a 95 eg with a jdm b18c and ex harness. Which wires go to the IAT (the plug on top of the IM), the IAC (bottom of the IM located on the iac valve. Also where is the IAB plug located? I made a mistake of thinking that the IAB was iac valve. Thanks in advance for your help.

10 - IAT
14 - IACV
15 - Ignition Output Signal
20 - Electrical Load Detector
21 - VTEC Solenoid
22 - VTEC Pressure
Check and make sure you don't have the IACV and IAT plugs switched, they are the same style plugs and near one another. The VTEC codes mean you probably never completed wiring up from the shock tower down to the ECU. Since you are using an EX harness those wires are embedded but only on the engine harness itself.
