4 wire O2 sensors from RP???
Hi guys,
How accurate would this Greddy 4 wire O2 sensor and Gauge be? Are these better than the standard 10 LED
Air/fuel gauges out there?

Where do the 4 wires hook up? The factory use only one wire. I imagine1 for signal to Ecu.
2 for ignition on... heats it up quicker
3 for ground
4 for????
thanks for the reply,
jc.
