Alright right now I have a B16A with a 93' LS Tranny in my Civic but its just not enough for me so I'm swapping in a built LS/VTEC engine. The LS/VTEC has a B18B1 block with a B18C GSR head. My concerns are about the whole IAB thing. I'm not sure on how to do the wiring for everything to work because I'm going to use a P72 ECU. So can somebody help me out thanks? Also should I get a OBD0-->OBD1 Jumper Adapter?

 

when you order the obd0->obd1 conversion harness it will come with wiring instructions that are easy to follow.
