Troubleshooting Brake Controller Install on 2019 Jeep Grand Cherokee that Shows Short Error Message
Question:
Just bought new takonsha brake controller for 2019 grand Cherokee and used the cable that came with the trailer tow package. Found the plug on last side under the dash and did the exact hook up as per the instructions. Controller shows short somewhere. Is there something Ive missed on this hook up which was supposed to be plug and play?

Expert Reply:
Sounds like you installed your Tekonsha brake controller like P3 part # 90195 using the included factory trailer wiring connector. Since you are seeing a short message on the controller that would indicate to me that you have probably wired the controller's wiring to the wrong wires of your install harness.
The blue wire of the controller should run to the circuit labeled brake output, red wire to stoplight circuit, white wire to ground, and black to 12 volt power. If you are seeing a short on the brake controller most likely you have the black wire ran to the ground. You might check this and other connections that were made.
