Ok here's the deal. Ive got a 93 OBD1 LS Motor in my 89 std hatch. I've done all the other obd0-obd1 conversions except for the 4 wire o2 sensor. My obd0-obd1 conversion harness did not come with the o2 sensor hookup. Where do i hook them up at the ECU? I un-loomed the o2 sensor plug from my spare LS harness so ive got the plug with plenty of wire to hook up to the ECU. My question is where do these 4 wires hook up?

White ----------------> Pin?
Orange/Black -------> Pin?
Green/White --------> Pin?
Yellow/Black --------> Pin?

 

Also would not having this hooked up prevent my car from starting? It hasnt started yet since the swap and I was just wondering if this could be the culpret? Any help is greatly appreciated.

 

This is what I did for my O2 sensor -

For the record, this is the correct destination for the wires at the oxygen sensor plug and their destinations with the harness-
Orange/Black - Heater (ECU A6)

Yellow/Black - Injector 12 Volt
Green/White - Ground

Hey thanks a lot!

 

o2 sensor ground on obd1 pinouts is D22

can i connect the o2 sensor ground on ( A23 or A26 or B2 ) ?

 

Why would you even do that? just hook it up to D22 just like you know you should.
