I am creating this post in order to make sure that I am getting this part of the installation right. If Im doing it wrong let me know. I am dropping a b16a obd0 into my 1991 honda civic hatch this weekend and I have an issuse that I was hoping someone can help me with

Besides adding wires for the second o2 sensor, the vetc and the nock sensor can I just plug my wiring from my pm5 cpu into the pwo cpu that came with the motor? If not does someone have a link to the pinouts for the pm5 and pw0 cpu.

Thanks

p.s most of the FAQ's on this issue are all dead links which is why I am asking this.

 

if your asking if you can plug a obd0 ecu into a obd0 car then yes you can.

 

PM5 is a dx harness (dpfi)

yes it will plug into obdo but you have to add addition wires like you stated.

also need to add mpfi wiring as well.

I dont think obdo's have knock sensors.

mine did not.

I had to add second o2 sensor, vtec wires and that was it.

I have a si so I already had the mpfi.
