Trailer Wiring Harness on a 2012 to 2014 Honda CR-V Does Not Work After Installation

Question:

I assemble all the electric circuit as shown in your tutorial video, placing the fuses and when testing nothing happens, the car lights work correctly but the rest not. What can i do? i checked the cables and nothing seems to be out of its place.

First you will want to make sure that the small fuse included with wiring harness # C56158 is installed in the correct location. The small fuse is supposed to go into location 10 in the fuse panel under the dash. Check to make sure the fuse is not blown.

The larger fuse needs to be installed in the fuse holder attached to the harness. Check it too to see if it is blown.

And finally, check the white ground wire. If it is at a shared ground location or the surface it is attached to is not bare metal (even paint will have to be sanded away) then the harness will not work properly.

I have included a link to an article that will help you troubleshoot further.
