Since you have a 7-way on your 2007 Toyota Tundra the best solution is going to be to replace the connector on your trailer with a matching 7-way like part # H20046 and then run the yellow wire of the 7-way to the reverse lights.

Whenever possible we try to avoid adapters as they end up being just another component that can potentially cause a problem. The simpler the approach to wiring the better.

What you have is a 5-way with a double wishbone, which means it is likely a double wire for marker lights as well as a double ground. You can replace your 5-way with another wishbone-style but it does not need to be a double wishbone with 7 wires,…

Answer 6

We definitely have what you need to replace the 5-Way connector on your boat trailer, but there's not going to be a pre-made 5-Way harness that includes 8 wires. As you mentioned the most you will likely find is a wishbone harness like #A25W5B…

Answer 7

What you have is a 5-way trailer connector with a wishbone running light circuit and 5th auxiliary circuit. The closest thing we have would be the Wishbone 5-way Part #A25W5B. This has a wishboned running light circuit, but the 5th circuit is not.…
