7-Way Trailer Wiring Harness for a 2004 Toyota Sequoia and a 2006 Toyota Tundra

Question

Question:

Will this harness fit a 2004 Sequoia an a 2006 Tundra? My sequoia only has the plugs connections under the vehicle. Will anything else need to be purchased to make this work?

I do have a wiring harness for both vehicles but the wiring harness for a 2004 Toyota Sequoia is different than the wiring harness for a 2006 Toyota Tundra.

For your Sequoia, you will want to use the Hopkins Plug-In Simple Vehicle Wiring Harness part # HM11143384 which will give you both 4 and 7-way trailer connections. The harness offers a simple plug and play installation that will not require you to cut or splice any wires. The pigtails that will need to be used to install this harness are near the drivers side tail light.

For your Tundra, if you also have two pigtails near the drivers side tail lights then you will want to use part # HM43385 if one of the pigtails has 3 pins and the other has 4 but if one of the pigtails has 2 pin and the other has 5 then you will want to use part # HM11143395. This harness will also give you both 4 and 7-way trailer connections which will not require any cutting or splicing.

However, if you do not have these two pigtails near the drivers tail light then you will want to use the Vehicle Wiring Harness part # C59236 for a 4-way trailer connection and then add the Universal Installation Kit for Trailer Brake Controller part # ETBC7 for both 4 and 7-way trailer connections.

Please let me know if your trailer has brakes and I would be happy to recommend a brake controller and the correct adapter if available.

If you have a 2003-2006 Toyota Tundra the 7-way wiring harness part #HM43385 that you referenced would essentially be the exact same thing as going with the Toyota brand connector. Most likely the Toyota connector does not have the 4-way option that…
