I'm not entirely sure if the harnesses are the same so to be safe that is why I said 07.
The harness in question is on the dome light assembly and has the plug ins for the bulbs and the switches to turn each bulb on individually. None of the few U-Pull Its around here seem to have 7th gen GP's or else I would go local.
Let me know if you got one and what your price shipped to 15478 would be.
