Havent done my swap yet one more wireing question

[Scott82]

Ok, I Get the P28 ECU, The 92-95 civic ex wiring harness complete from ECU to Motor. How and Where do i run the Harness thru the fire wall. I have never done a motor swap where i have to change the wiring harness so i have no idea how to run it thru the fire wall. I just want to figure out what hurdles i have to jump before i get to them. 89 CRX HF to D16Z6 92-95 Civic si motor and some delsols

There's a big hole in your firewall (maybe even 2) right near your ECU where the harness comes out. You really can't miss it, man. There are 4 bolts holding the ecu cover in place, if you unbolt them you'll see the wire harness connections. Honestly, you probably don't even need a full EX harness, cuz your HF is already wired for MPFI. All you really need are a couple more wires which connect to a couple of connections (one is the vtec solenoid). I think you might can get a OBD0 to OBD1 piggyback for cheap.
