So Im beginning to work on swapping a obd1 b16a from a SIR II into my 90 DA integra that previously had an ls vtec swap running OBD0 PR3 ecu. I will post pics and questions after I pull out the old motor, I just picked up the B16 and havent pulled out the ls vtec yet.
For now I just am wondering these three things....

1. Its already wired for vtec but I know there was no knock sensor installed on my block so Im wondering how to run the wires for the knock sensor since they modified my ls harness when installing the ls vtec.

2. Will the OBD1 distributor plug into my harness or will I need to use the OBD0.

3. Will I need to use the 4 wire O2 sensor or should I use the 2 wire that the harness is equiped with now.

Im sure I will have more questions as I progress and pull the motor out and have a better idea of exactly what the modifed ls harness consists of but these are just preliminary questions running through my head. Any help greatly appreciated. Also if you think of anything that might need to be done to make the modifed LS harness work with the obd1 sirII motor please mention it. Long day and I may be overlooking something obvious...

 

Can anyone tell me if I will be able to run the obd1 SIR II motor with my OBD0 pr3 ecu. its whats currently running my ls vtec in my DA and I dont have an obd1 ecu. Please help....

 

someone help with wiring please.....
can I use obd0 dizzy from ls vtec and be fine running the motor on obd0 pr3??????????
