hey i have a 93 prelude si with the h22a swap in it. i am running the h23 harness. i need a on sensor but i dont see anywhere on the harness where the sensor would plug in? can anybody help me out with this?

 

anybody.....?

 

run wires straight to the ecu.

 

it's a 4 wire plug, im not sure of the colors and i gotta go, look in the faq for the ecu pinout and it will tell you what color wires the o2 sensor uses, gl

 

thanks!! let me know as soon as u find out. and what brind o2 should i buy?? bosch..oem??

 

I hear good things about bosch, but oem is never a bad option. It would depend on price difference for me. If you want o2 wire colors, go to o2simulator.com and look at the resource section. They'll tell you what color each wire is.

 

thanks for the help...but this is very strance seeing how i can not find the plug for the o2 sensor?? would it be located under the car somewhere??
