I just need to know what needs to be done.

Would it just be easier to use all OBD-1 sensors from the stock motor?
Do the OBD-2 sensors work with just wiring harness hacking?
Can I use the ECU from the OBD-2 engine with a conversion harness?

Thats it, don't just tell me to search, if you do you're just a post-count ***** on the internet.

Links appreciated also, no need to type things i'm sure have been covered 9.8234E4 times.

 

What motor are you using?? d16y7, D16y8 d16y5??

 

use the complete engine, assesories, and harness, with your chassic harness and use an obd1 ecu.

 

What about the sensors if I use the stock wiring, just change the plugs but use stock harness?

Its a d16 going in, not sure which one.
