Question:
I have a 2012 Nissan Frontier that is pre wired but I need a 7 pin plug in on the back of my truck. My question is can I get the item C56225 for the harness and relays and not use the 4 pin and get a different 4pin and 7pin combo to plug into the existing wiring?

Hi Michael; we don't have any options that let you choose your own connector. However, you can use the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118281. This comes with the relays and a 7-way only. Since this wiring harness uses a US Car connector it can be traded out for a different connector like the # HM40975 which has both a 4-way and 7-way connection. If you need anything else feel free to reply below.

Hi Michael, did the T-One Vehicle Wiring Harness with 7-Way Trailer Connector work out for your Nissan Frontier? I'm curious to know if swapping it with the 7- and 4-Pole Trailer Connector was a good solution for you. Your experience could really help others with similar setups!
