sorry guys i searched and really didnt get what i was looking for. what i need to know is what wiring needs to be done. the ecu is an obd1 ls,distributor is a obd1,injectors are obd1 and the engine harness is for the 89 si. blown90hatch made the conversion harness for the ecu. what else if any needs to be done? do the injector clips need to be modified? also the distrinutor,whats needs to be done there? TIA

Talk to blown90hatch, he did a write up on OBD0 to OBD1 and what all is involved if I'm not mistaken. Since you already have MPFI wiring, it will make the conversion easier. You'll need to rewire the injectors, eliminating the resistor box. You'll have to run wiring for a 4 wire O2 sensor, some distributor wiring (plugs and such), etc. It's not that hard when you have it all in front of you, it does take some work though.
