    since the HF was already MPFI, you won't need to do any wiring to the engine - use your HF engine harness - it should plug right in to everything - you will have a connector on the HF harness that isn't used - it went to the EGR valve - the vacuum lines for the B18A are similar to the HF - the HF has a couple of things for the EGR in the control box on the firewall that have vacuum lines to them - you won't need the ones for EGR, just the MAP and purge solenoid - use the PR4 OBD0 ECU

    you will need to swap out your front knuckles/hubs for ones from 88-91 Civic/CRX DX or Si in order to use the Integra axles
