    Hi, I'm wondering if I can replace the factory 7 pin with the modern 7pin/4pin combo oem that Toyota sells for the newer tundras. The connector on the back looks exactly like the back of my single 7 pin connector.

    You would have to check the wiring if you are talking a plug an play thing. If not plug and play it would be fairly simple to re-wire it. Also, 1st gens did not come with all the wires to the 7 pin plug, for it to fully function you need to run a couple of extra wires. If I remember right I had to run the trailer brake wire and the power to trailer battery wire. The early ones got the 7 pin plug but it was wired about like a 4 pin plug. Also, if all you want is the ability to use a 4 pin plug you can get an adapter that plugs in to the 7 pin and converts it to a 4 pin...they are fairly cheap at Wally World.

    Interesting my 06 is wired for brakes, tow package with a connection for a brake controller. I'll have to check the diagram.

    My Taco Pro has that also. At least in the early 1st gens they supplied a 7 pin plug but no wiring for a brake controller etc. When I did mine we had to tap the brake light power and also run a wire or 2 to the rear. From the factory it would run the lights on a 7 pin plug, but no brakes etc....
