I have a 1997 Civic EX w/ a B18c swap.. Here's my question
- Which AC System do I need? From an Integra or for 97 Civic?
- Which Engine Harness SHOULD I be running? I have an Acura Harness right now that came w/ the swap but it's causing some issues w/ ECU

I was told to put the 97 Civic EX 5spd w/ VTEC Harness back in and splice what I need off of the Acura harness just wanted to ask before moving forward.

You can either use a 99-00 Si harness or use your stock harness and splice the wires that you need. The Integra hardness won't work because it's a 2 piece harness so don't even bother using it.

AC system you can use your stock AC lines and compressor with del sol vtec bracket.

Reason no one probably answered is these are easily googled questions and you could have searched.

^^ he cannot use a 99-00 si harness

you reuse your stock harness. almost all of it will plug in. you will need to rewire the IAT plug, plus add iab wire if you're using it.
