i have a 88-91 si head with obdo dizzy..


im a newb thanks.

 

What ECU are you running?
If your ECU supports a 4 wire, then that's the best way to go.
The readings will be more consistent since there is a heater element in there.
1 Wire relies on the exhaust gasses to bring it up to operating temperatures.

you can use any form of crimps or connectors to attach the wires.
Using a stock connector would be best in the sense that it will make swapping out O2s and disconnecting easier.

 

It has a pm5 in it. I don't want to run any wires to the ecu just a plug to hook these 4 wires too so I can plug up a o2..she's crackling and running rich. Just not sure if I need an obd0 or obd1 plug.

I've always done b18 swaps..I'm still a noobie on this

 

PM5 uses a 1 wire 02

 

can i use a different o2 then the 1 wire one without having to go crazy changing or wiring up things?

I have a spare harness that came with the car with a small square plug with Black red yellow and white wires to it.. lots of missing plugs but this is still intact.
