Finally got my Speed of Sound gauge pod installed, water temp gauge and Raptor shift light hooked up. Now I just need to get my A/F gauge hooked up. Instructions say NOT to hook it up to the wire going to the O2 sensor, but instead hook it to the same wire in a harness somewhere. The wiring harness that all four of the O2 sensors wires come from runs across the top of the transmission and is impossible to get to. So my only other ( and more desireable ) option is to find that harness in the engine compartment, locate the wire in quesiton and splice it in there.
Does anyone know what harness and wire I need? I have seen the wiring diagrams from the service manual DVD. Kind of useless. According to the DVD, practically everything going to that harness connects to a red/yellow wire. :madas: I am pretty sure that is not the case! It is easy enough to see where the harness comes up in the engine compartment, but it almost immediately joins in to a main harness. So if anyone knows where I could pick up the wire I need perhaps at the power distribution block or the PCM, the info would be greatly appreciated.
