i have searched around this forum and didnt find the right information i needed.

i have a 96 civic ex and im in the process of swaping in a OBD1 b18b motor but have a few things taht concern me.
i have a obd2 ecu from a b18band was wondering will that work? also, do i have to get a LS engine harness or can i use a different harness? friend told me i can use a dx harness. is that true?

i would apreciate all the help and information. been waiting for about 8 months for a freinds to help me get my car running but i dont think i can wait ne longer so i decided to do the swap myself.

As long as the ecu is obd2a you should be able to use it. Also the harness in your car should be able to be used.

so the obd2 ecu will work with the obd1 motor?

Im almost positive you will need a conversion harness.

Obd2 ls engines have a knock sensor, obd1 do not - you'll throw a code for that. So...get an obd1 P75 ecu and conversion harness
Just use the current civic engine harness though - you will only need to extend IAT to the intake manifold and EVAP - no need to get another harness. There will be a few extra connectors, but just bag/tie them so they dont get wet.

I hope you have the correct mounts.


edit**
Oh, if you want to add a knock sensor and use the obd2a ecu, Ive been told people re-tap the upper-inner alternator mount hole for a sensor there.
