sup guys im startin a new build and i just wanted to know what wiring harness do i have to use, do i need the OBDO or can i run the OBD1? and if i run the OBDO what do i need to do to wire it into my car thats OBD1? thanks for the help

 

well if the motor is obd1 your car is obd1 so you would use the obd1 harness..

 

is the B18a1 OBD1 I thought it was OBD0

 

b18a is obd-0; b18b is obd-1 or obd-2.
you could use the same harness that's currently in your car.
since it is non-vtec, you don't need the knock sensor, vtec solenoid & oil pressure switch to be wired.
you will need to change out the injectors for obd-1 versions.
you will need to use a single 4-wire o2 sensor in an obd-1 exhaust manifold.

 

b18a1 is also obd1

b18a1 is from a 90-93 teg..90-91 were obd0, 92-93 is obd1

 

oh yeah - '92 and '93...the bastard child years: caught between da/ef & dc/eg revisions.

my bad - good catch.
