the ecu only relies on data coming from the sensors on the motor, the hard part is lopping the harness down and matching wires on each side of the fuse panel on what needs 12v and 12v switched and ground , the pain in the ass part if you are wanting to delete all that jazz is messing with the main relay etc, it would be easiest to use minimal wiring from that harness to make it run and add your own fuel pump/wiring etc to eliminate the main relay , I looked into doing all this with a chopped down crx harness was my original plan and ended up being a huge headache
