7-Way and 4-way Trailer Connector Recommendation for 2004 Toyota Tundra with Factory Tow Package
Updated 12/01/2014 | Published 11/30/2014
Question:
I need to replace my factory 7-way and want to add a 4 way with it. Looking at #HM43385. My truck has slightly different color wiring - photo attached. The left turn signal is a red wire and the backup is a yellow wire. There is no purple. All the other wires are as shown in your photo. The pins on mine are identical to the ones you show. Any thoughts on why mine is different and will this part work?

The colors of the wires of the # HM43385 may not perfectly match what you have on your 2004 Toyota Tundra, but as long as they functions match up (they should), this product would be exactly what you need.
You can verify that the connectors you found match pins of the diagram with a circuit tester like part # PTW2993. You will need someone to apply the different taillight functions while you test the pins with the connector.
