what colors ya got? i'm diggin for my wiring diagram. black us usually ground so we can pretty much rule out black and black with any tracers.

Did you get it calibrated for WOT. Otherwise its completely worthless.

Nope.. I did'nt calibrate it yet. I'm going to run the wiring (with a quick disconnect) & install the pod. Thanks for the link.. I wasn't sure where I could get it done.. :biggthump

Anyone know the wiring yet??

Thanks

Not sure if this helps, but this is all I know without looking through a wiring diagram:

From the Innovative Motorsports LM-1 Wideband Sensor Manual:

c. Vehicle has a 3-wire sensor:
Typically the 3 wires are: heater power, Ground, and sensor element connection. Generally they have 1 black wire and 2 white wires. Connect the black wire from the EFI computer to analog output 1 of the meter. Leave the other wires unconnected but make sure they cannot contact any metal parts or see above. If the wiring colors are different, then heater power can simply be determined by measuring the voltage on the wires when the engine is running. The wire showing 12V or more is the heater power. The sensor element connection voltage fluctuates around 0.45V when the car is warmed up. Wire analog output 1 directly to this wire. The Ground connection has low resistance to chassis ground (less than 1 Ohm). Measure while the engine is
off.

d. Vehicle has a 4-wire sensor
Typically the 4 wires are: heater power, heater ground, sensor ground, and sensor element connection. Proceed as for the 3-wire sensor.

I don't know what you're looking for as a "high" wire, but you'll need a multimeter to determine which one is running power (as specified in the above instructions).
