I am pretty sure all OBD 2 engine harnesses are a one piece design where it runs all the way to the ecu connectors ( under the dash obviously). The OBD1 harness should stop at the shock tower like you stated before.

 

Yea the itr motor in my car now is a obd2 which plugs up at the shocks tower..i just wanna know is the obd1 harness going to plug up there also when i change over the swap..putting a obd1 motor and harness in a obd2 car????

 

Yes, an obd1 integra engine harness will plug right into the obd2 shock tower harness. Remember to keep the alt and distributor with that obd1 engine

 

y-not u keep ur cars engine harness and he keeps his

 

Keep your distributer and switch your injector clips to obd1 so you can run aftermarket injectors for when you get tuned.

Keep your harness.
