at frist i thought cuse my car were in the 96 throught 99 are it would work teach me for think

 

run the ecu thats in the car (the 99), use the harness (the 99) from the engine that was in the car... thats it done

 

dont have the 99 engine or harness jsut the shell and the fuse box harness i had a 97 civic i creasehd torque stear gone bad, and swaped the motors till i came to this fork in the road

 

do you have the rest of the 97? just swap EVERYTHING over? idk dude

 

yeah,use the ecu and everything from the 97, and you should be golden.

that wut i thought im only 17 and was setling a bet with my dad thanks guys

 

The ECU plugs are different between cars, you need to run the 97EX ECU and engine harness, and swap over the under dash harnesses if there is still wierdness.
