My vehicle is equipped with a seven-wire trailer towing harness. Harness is not active. The owner manual states that the fuses for those two circuits are installed in the under-hood electrical center, but the wires are not connected. Where can I find the wires that need to be connected?

Hi,

Are you referring to a factory harness that came with the vehicle? If that is the case, there will likely be a plugin for the harness under the rear of the vehicle (driver's side I believe) along the frame rail.

Let me know if that is what you are referring to.

Take care,

Joe
