Definatly not the first person to try this, but cant find any info on it... Swappin in a OBD1 B-16 motor into a 91 DX. Dizzy wiring/VTEC wiring checks out ok, so my question is reguarding the injector wiring.

The motor came with a complete OBD1 wiring harness so I cut the colored wires on the injectors leaving all the yelloy/Blk wires still connected to the large grey plug at the end. There were 3 other yellow/Blk wires. One of them went to the 4-wire O2, another to the IACV, and the 3rd yellow/Blk I cut coming off this. Where does this last of the yellow/blk wires need to go?


Also, this is the jumper harness im using.....


And the instructions...


It lists 2 red wires as power and 3 black wires as grounds... Does it matter which of the 2 red wires or 3 black wires go to the corresponding sensors or do they all supply power/ground just the same?

Any help is much appreciated. Thanks guys.

Anyone have some input here?

Your suppose to use your stock dx wiring harness and do the multi port conversion. I feel like you just made a lot more work for yourself and confusion. The obd1 wiring harness is not going to plug into your car harness.

I did a a obd1 conversion is my 88std and the only changes I made was the jumper harness like you already have, 4-wire oxgyen sensor, OBD1 distrubutor, and a chipped p28. I didn't touch the injectors. I also made the minor changes to the distrubutor wiring, but nothing serious.

I am still using the stock wiring but since i had to use the OBD1 injector plugs instead of the clear ones, i left them attached to the grey plug at the end that goes in place of the resistor box.
