Got a 91 HB with b16A2/p28 ecu. How would I wire a 4 wire O2 sensor onto the p28?

I would help you out, but I am still trying to figure out the pinouts for mine...

I cant stand it when people dont do things right the first time!

Or when you have extra wires and no idea what they go to! ?

I have been looking for stuff on here that has the pinouts for my wire harness?
I cant seem to find one that matches, all of them seem to be different!

I got the chart for my ECU (PR3)

I have a 91 Si, and I need a chart with plug A B and C wire colors, and the locations they go in!

Can anyone help me out?

That is what I thought!!!!!
But then I read that you can use 1 if you just connect the 2 sensor wires together....

I dont want to do that tho... I want to run the JDM manifold, with 2 sensors...

So what pin is the 2nd sensor?

www.RYWIRE.com helped me out over the phone with my wiring, great guys. And if you don't want to do it yourself, then they sell kits for conversions including OBD0 conversions and 4 wire O2 sensor conversions...
