02 heater pinout
not on an rx7! can someone tell me if the o2 heater pinout supplies 13.8 volts directly to the 02 sensor??
its on a celica gtfour,my loom currently doesnt have a heater wire but i want to use one,i have a 4 wire 02 sensor from my previous haltech install,from what i can see i run the 02 output to the pfc and run the heater output from the pfc to the 02 sensor and ground the middle 02 wire?
any help gratefully recieved!!!

Since the RX7 did not have a heated O2 sensor, our PFC does not have that option.
You need to go to the correct PFC forum for your model.

Just make your own wiring for it. You can have it constantly heated, or place a manual on/off for it, or have it come on and then turned off by a timer.
Basic simple wiring.

That is irrevalent and places more strain on the PFC.
