No, I haven't tested it or hooked it up yet. I've got the battery disconnected and my hands are going numb in the garage, still below freezing here. It was SNAKEWOLF's post that lead me to look at the "other" bundle of wires. On his advise I went back to the Manual and looked at 8W - 91 - 2 8W-91 CONNECTOR/GROUND/SPLICE LOCATION (Behind the Passenger Footwell) for pin connector (C201) for the back-up signal sensor and elusive GY/YL wire. It tells me to go to Fig. 2. Well Fig. 2 shows me the left side engine compartment which I figure is another red herring but right below it is Fig. 3 which shows me the right side floor and a big old arrow pointing to C201. So this tells me there's gotta be a GY/YL wire in the passenger footwell going to C201. I know where it's not so I unwrap the "other" bundle of wires and eureka! GY/YL wire. I figure if I pull up the carpet I'll see the GY/YL wire going right to C201. Ill confirm on the weekend but if you get there before me, let me know.
