Right, I noticed on another forum someone asking how to wire an a/f ratio guage to their saxo, VTR/VTS im not sure which, I know a vts has a 4 wire sensor (internally heated) and his guage has 3 wires, so their are 2 feed wires and a + and a - on the sensor, how is it wired up to the guage?

I assume from the guage (3wires) one ignition live, one earth and the other a signal wire? so that leaves 1 signal wire from the sensor?


very curious about this as ive tried looking on gizoogle and cant find much help.
