Any help on a 99 Infiniti Q45 is appreciated; I'm having a tough time with the FSM scans. I'm looking for the colors of and the easiest places to tap the reverse and VSS wires. Thanks.

Speed Sense PINK/BLUE (AC) PIN 7 AT CCM LEFT OF STEERING COLUMN

That's the only thing I can find for VSS wire, your reverse lights shouldn't be too hard to find, they're usually in the driver's side kick panel in the wire loom heading towards the rear of your car. If you can easy access the wiring going to your rear lights look for similiar wires in the kick panel.

Thanks.

Can I tap the reverse pin on the harness to the instrument cluster which leads to the gear indicator light on the instrument panel? Will that give me 12v on reverse?

Also, can I tap the VSS at the speedo behind the instrument cluster?
