I wish I could have done that with mine. I used a 2nd generation GA16DE, so I couldn't use much of anything (except alternator harness) from the GA16i. Thanks OBD2... what a pain. Looking back, I should have just used a 1st generation GA16DE, and kept the coil to distributor and OBD1 setup. Swapping things would have been much easier like you said

. I had to put the ECU (passenger floor) where I did because the harness wouldn't extend any further into the cabin.
