GPSE, I went by location on the connector. The colors weren't an exact match but were very close. I found that everything on the wire list was correct, at least in my 2000 GT. Everything is working great. I did have 2 wires from the original connector that weren't used but I put shrink tube over the unconnected ends and wrapped them into the harness. I'm debating whether to go for the HUD now!
