Drop Panel under dash to locate taped up wires

On the Tekonsha Controllers I sell, The power wire is Black, it would hook to the heavy Orange wire. The Heavy Blue wire hooks to the Heavy blue wire. The small Blue wire is the brake light switch signal, it would hook to the small red wire on the controller. The black wire is ground, and hooks to the white wire on the controller.


Under the hood, locate the folded up wire next to the fuse box and hook it to the stud. Install fuse if needed.
