i have a jdm d15b and i was wondering what i needed to finish this swap. i have the complete motor with trans. i have a obd2 to a obd1 conversion harness. i also have the p08 ecu. will the 4 wire o2 sensor work on the p08 ecu, or will i have to go with the p28 ecu? and what about the iavc wires? i have a 3 wire right, and the d15b has only a 2 wire iavc? how do i change that? and one last question, what abou the distrubiter plugs... they are also different, they have different plugs on them? how do i fix that? will it be safe if i just use a d16z6 engine harness, will it plug and play? any info will help. thanks in advance

The P08 uses a 1-wire, but the 4 wire will work with the heater unpowered which is fine. Nothing is is needed on your part.

and what about the iavc wires? i have a 3 wire right, and the d15b has only a 2 wire iavc?
Just moving one of the ecu pins is all that is needed. Move the black/blue wire over to the edge A12.


what abou the distrubiter plugs... they are also different, they have different plugs on them?
I cut the plug off my OBD2 dizzy and cut the 2 dizzy plugs off of an OBD1 engine harness and made and adapter. Just match up the wires. That way you'll have a OBD2 to OBD1 dizzy adapter.

will it be safe if i just use a d16z6 engine harness, will it plug and play?
They are not compatible at all. Just save it for the future if you need any plugs.



One other issue is that you might want to switch IAT plugs so you can use the manifold placed on on the D15B engine instead of using the intake tube placed one. That way if you ever go turbo it will already be done. Just cut the plug off and solder in the plug from the D15B harness.
