obdi Hdeucedeuce

[1slowcd5]

I feel like this has been answered somewhere but I cant find a clear answer soooo. If I were to swap in a OBDi motor/ecu into a OBDii car, what would i need to modify, other then the jumper harness

Run a OBD2-OBD1 conversion harness, reroute the crank sensor wires to the distributor to still be able to use the obd-1 dizzy.
Run the vtec wire. You won't need the knock sensor,iab circuit if running a p28. If your not, you'll need to run them through the harness.

Once again, if using the p28 you can delete the egr. Extend the iat,iacv wires and just reroute the o2 sensor wiring. Just unwrap those wires from the harness and reroute the 02 wire to the back. No need to extend it
