im hooking up a air/fuel tomorrow and i need to know what color the wire for the sensor signal is on my rt... i have 4 wires and heres the colors and were they are from. t/w or o/t from c124 b/lbl from c14 and c315 b gound and o/dg from fuse a... need answer thanks
It should be the BLK/ LB wire (although my wiring schematic shows that wire BLK/ GREEN), It will be the only circuit that have a varying voltage between 0-1 volt. Probe the wires with a DVOM and determine which wire has the signal, one wire will supply B+ for the heater, one is heater ground, one is reference supply voltage and one is signal return The signal return is the circuit you need to tap.
