What year, make, model, engine is this?
One more thing, is this the cartier, signature or executive?
So you have 12 volts on the white/pink wire going into the transmission position sensor but none coming out on the red/light blue, with the key on start and vehicle in park or neutral?
I looked up the wiring diagram for the cartier but normally they are all the same anyhow. This should be a aod-e transmission and if so there is no adjustment on that neutral or range sensor, so if you have voltage in but not out, I would assume the sensor is bad. try holding the key on start while moving the shifter from park to low and back and forth a few times, if at any spot the starter engages, then let me know, if not, take that sensor back and get another.
I don't see a red/yellow, maybe that's for the backup light or something but if the white/pink wire isn't hot with the key on start then the problem isn't the neutral sensor as of yet. It's before that and could be a fuse, relay or ignition switch. Does this have anti-theft?
here is the wiring diagram,
If it has anti-theft, it might be the relay both either with or without anti-theft, make sure that fuse P in the engine compartment fuse block isn't blown and has power to it all the time, even with the key off.
Just as I assumed, that red/yellow wire is for the exterior lights, specifically the backup lamps.
