Adding a 7-Way Trailer Connector to a 2009 Hyundai Santa Fe with 4-WayTrailer Connector


I installed part #118258, now I see the trailer has a 7 way flat pin connector. Is there an adapter that will connect the 4 way flat on the vehicle to the 7 way flat on the trailer?

In order to add a 7-Way trailer connector to your 2009 Hyundai Santa Fe on which you have already installed a 4-Way (118258) you have a couple of options. First, if you just want the basic lighting functions and nothing else then you would just need an adapter like # 37185. The 4-Way end will plug into this adapter, then you will ground the white wire to the frame and tape up and stow the other wires out of the way.

If there are functions on the trailer like electric brakes and 12 volt accessories then you will want to use # ETBC7 and a brake controller. The ETBC7 will provide the 7-Way and the accessories needed to wire it in and to wire into a brake controller. For a brake controller I recommend the P2 # 90885 because of its reliability and ease of use.

I have included some links that explain the ETBC7 installation.
