Will Adapter 7 Pole to 4 Pole and 5 Pole Work On My 2010 Toyota Tundra With Tow Package

Question:

I have recently purchased a 2010 Toyota Tundra with the towing package. Would the #37385 match up without making any wiring changes to my boat trailer, the trailer is three years old. The trailer has a five pin flat connector. The fifth pin is for by-passing the surge brake hydraulic pressure when backing. Thank you.

If your 2010 Toyota Tundra is equipped with tow package and factory 7-way on the back of your truck then yes the Adapter 7 Pole to 4 Pole and 5 Pole, part # 37385 will match up perfectly. The 5 pin flat connector on your trailer will plug directly into the 5 pin outlet on part # 37385.

The fifth pole on the 5 pole adapter should be the same circuit as the center pin on the 7-Way. This is typically wired as reverse lights if it is an OEM 7-Way. If it is aftermarket, chances are good it was wired for reverse lights or possibly 12V power feed.
