i have an 87 turbo 2 rx7. i bough a wideband a/f and controller and need to splice the wires of the connector. my o2 sensor was never connected to anything so i dont know where the connector is.. any help would be greatly appreciated. thanx.

 

Just look for a solid black wire hangin around somewhere near the BAC

What controller did you get? I have an LC-1 and I'm having a hard time getting the narrowband simulator to function like stock.

 

you can replace your stock sensor w/ a wideband? don't they burn out quicker? aren't they supposed to be mounted further downstream in the exhaust?

 

im not really sure how that works. but im pretty sure having no o2 sensor connected to my ecu is giving me a number of my problems. this why im asking. i also have the lc-1. anyone done this before?

 

Connect it direct to ecu harness, pin for o2 is 2D..
