hey guys i searched but couldnt find anything that told me exactly what i need to do here. ive got a 94 gsr in my 95 cx hatch with a p28 ecu. can i just keep the 1 wire on the cx? or do i have to use 4? if im going to use the 4... where exactly do i run the other 3 wires to?

 

You need 4. You'll need to buy a 4 wire o2 sensor, and it should just clip into the stock harness. I'm *pretty sure* the cx harness is the same as the rest of them...

 

Here's an active thread with guys that know a lot more about this than I do:

You'll find what you need there

 

ok thanks man.... yeah i read that only the cx uses a 1 wire instead of 4
