Question:

2019 Honda Odyssey Rear Fuse Panel Slots 10, 11 and 12 are pre-pinned for Trailer Harness. Could you tell me what each slot is specifically for? I am blowing a fuse and need assistance tracking down what the slot is for so that I can troubleshoot the issue.

I would be happy to help you identify the functions, but besides knowing that fuse 10, 11, and 12 in your 2019 Honda Odyssey are for the trailer towing functions, Honda does not list specifically what each one does.

Now there is a way to figure out, but it will require a circuit tester like # PTW2993.

What you will need to do is remove one fuse at a time and use the circuit tester on each wire of the 4-way connector and see which function is no longer working.

The function of the connector are as follows:

Brown wire is tail light/clearance lights
Green wire is passenger side tail light
Yellow wire is driver side tail light
White wire is ground which won't have a fuse

You should have one fuse for each function, and that will give you at least a good starting place to start the troubleshooting.

I included a link to a helpful article on wiring for you to take a look at.
