Ok so I just picked up a 91 CRX Si w/ a b16 OBD-0 swap. I was given this D&M motorsports harness and my only real question is that it doesn't have the 10 extra wires like most companies. It only has 5: vtec pressure switch, vtec solenoid, service check signal, knock sensor, and primary 02 heater control.

I know that the four wires for the o2 sensor are missing and not sure what the 5th one missing would be. If I'm running an S300, make the dizzy plug adapters, and connect the given 5 wires on the harness, can I just disable the o2 sensor and knock sensor and be good?

 

Mine had an extended ground wire for the service check wire so you can run it to a switch but you just need to ground it to check your cel
And if you want to disable them i don't see why you'd run the wires anyway so id assume itd work

 

the other extra wires are for GSR applications. IAB solenoid and evap purge solenoid.

If you disable your knock sensor and oxygen sensor you wont need the wires for them.
Personally, i would run them to the engine bay just in case you might want to change your setup in the future.

Btw, obd1 oxygen sensor have only 4 wire.
the 5 wire is for a VX which i doubt you are running a VX engine+ecu.

 

Alright thanks everyone. I was thinking of pinning in the four wires for the o2 sensor into the harness, so when I get a chipped ECU for this car it will run flawlessly as a daily. The S300 has to go back into my Integra eventually for that setup.

 

Both your Teg and Rex are slow!!!!!!!!!!!!!!!! :p

 

Yes, indeed they both are. lol
