Wiring a 2007 Hyundai Santa Fe with a Brake Controller and 5-Way for a ShorLandr Boat Trailer

Question:

Hi , I have a 2007 Santa Fe and may possibly purchase a boat with a ShoreLandr trailer that has a 5 way flat connector. It is using Electric over hydraulic brakes. I have installed the 4way wiring harness and have a bunch of questions: 1 Do I need a brake controller - I think I do. Can not find much info about this on the ShoreLandr website. 2 I have found the 4 way to 5 way adapter that connects the 5th wire to the backup lights. 3 All the wiring harnesses for the brake controllers show the 7 way round connector - which will not work. Guess there is adapters, but did not see the backup lights being wired in. This seems a bit complicated - not sure if it is doable. Regards

I can help you, no problem. I did some research on the ShoreLandr trailers that come with electric over hydraulic brakes. They also should come with the Titan Brakerite Electric-Hydraulic Actuator, # T4813102. You will need a brake controller that is compatible with electric over hydraulic braking systems.

The easiest to set up and to use is the Tekonsha P2, # 90885. If your 2007 Hyundai Santa Fe has a 4-Way trailer connector, we are part way there already. If not, you will need to install one, # 118415. I have included a link to the installation details and a video showing a typical installation for you to view. If the vehicle came with a 7-Way trailer connector, you can install part # 118258, to replace it with a 4-Way.

With a 4-Way installed, you will then need Hopkins Endurance 5-Way Flat Trailer Connector, # HM47900. You will need to cut off the end of the 4-Way and wire the bare wires to this connector. The blue wire should be the only one left . This connector is needed because the blue wire on the 4-Way to 5-Way adapters are not a heavy enough gauge for brake output.

The blue wire will eventually go to the brake controller in the vehicle cab. You will need about 25 feet of wire # 10-1-1. On end connects to the blue wire at the back, the other connects to the blue wire of the brake controller. The remaining brake controller connections are as follows.

Connect the white wire to the negative battery cable by using left over 10-1-1 wire and routing it through the firewall.

Connect the black wire to the positive battery terminal using left over wire, routing it through the firewall. It will first need to connect to a 20 or 30 amp circuit breaker and then to the battery. The brake controller instructions will tell you what size to use. For a 20 amp, use # PK54520, and for 30 use # PK54530.

To attach the red wire, you will also need a circuit tester, # PTW2993. On the brake switch located above the brake pedal, use the circuit tester to find the wire that carries a signal only when the brake pedal is pressed. If you find a wire that has a signal when the lights are on or turned signal engaged, it is not the correct wire. Once you have found the correct wire, attach the brake controller red wire to it.

If the break away system is not installed or is not present, make sure to follow the instructions for the Brakerite to make it functional. I have included a link to the Brakerite instructions that should help.
