I'm in the same boat, according to the instructions that came with mine
(autometer pro comp ultra lite) it says that 4 wires mean its got a built in
heater to heat the sensor, dont wann tap into those, can we say fried meter
?!?
Also I think your supposed to hook it up close to the computer, not under
the truck (its exposed to road conditions there).
If ya find out lemme know,
