I have a 99 civic ex coupe. I'm putting a 00 LS motor into it. The D16y8 is out and before i put the LS in, I was looking at the LS ecu, and the wire harness off the d16y8, wont plug into the LS ecu. my one buddy said I need an obd2b to obd2a jumper harness?
Any advice would help
Thanks

 

i think your buddy is right your car is obd2b don't think tegs switched till 01 ff-squad has some pics of the differance in the plugs good luck with the swap
