Hi all..

I recently installed an obd2a harness for a friend's civic em1 (obd2b)..

the thing is.. the obd2a engine harness has 3 plugs that fit directly into the ECU...

whilst the obd2b engine harness had 2 plugs that went into the ECU and a 3rd from plug is from interior harness..

deliema is now i have 2 plugs that are exactly the same that plugs into the ecu on the same socket , b/c im using an obd2a engine harness and obd2b interior harness....

does thisn sound right?
