ok i am gonna do this in a week and got most of the parts. just need headgasket and timing belt. i need a guide on the converting obd0 to obd1 cuz this is the only thing i aint never done. i will be using a z6 head complete on a 89 std hatch.

My main question is what do u do with the harness i got both harness complete but i have no idea if i use the 89 or the 93 or even what to splice together.

 

Use your stock harness. If it isn't already converted to MPFI, best to do it now. From there, change ECU pinouts from OBD-0 to OBD-1 through use of a harness or hardwiring. Run extra wires for VTEC, 4-wire O2 to engine bay. Enjoy

Lets say u have the head on and have everything bolted up. And have the obd0 to obd1 harness in place with a P28 and ran the wires for the vtec sol. and 4 wire o2 to the engine bay and splice them to the plugs and plug them to the sensors. what would be next? like the fuel injectors do u need to splice in the plugs from the obd 1 harness?

Janos</TD></TR></TABLE> Yup, that'd be mine I believe, I need to add some more diagrams to it...thanks for reminding me

 

That was fast!!


I checked it out. So i guess i have to regardless get a SI harness too?????? Even if i am gonna use the obd 1 injectors.

 

Ok according to these instruction on rywire.com i need that plug(which i have)


OK OK i know what i am trying to ask now.
