Alright guys im hearing problems that wiring a b series. Ok first of all its gonna be a ex coupe. So does the engine harness plug into the interior harness. Do i have to to change the interior harness or anything. Im gonna junk the sohc and im want to know what harness can i use and will it plug right into the interior harness at the firewall.

 

Will the LS engine harness plug straight to the regular civic harness. Im going to be running a obd1 and i dont want the plugs to be different.

 

What year civic? and what year integra? '94 - '01 integra (I think '92- '93 also) are a direct plug in to a '92 - '95 civic interior harness. If its a '96 - '00 civic you will need to modifiy the original civic harness.
