CURT 56378 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Select Honda Odyssey

I have no problem with this and it functions properly. I wish they had some type of cable management system when it isn’t being used, but that’s me just being nitpicky.

I had some trouble getting the back left panel off to route the cables behind it. It took some tough pulling, start with light pulling in multiple directions until you figure out where the plastic is snapped together. The plug fit perfectly. It has a cover plug that is just to protect the pins when it is not plugged into the vans fuse block. The sticker on the inside of the vans fuse lid shows you rhe fuse #s that match thee instructions I had to get creative with where to place the ground wire. I used several more zip ties than were provided to prevent loose wires and noises. Very pleased, worked on first try.

Bought this for our Honda odyssey, installed it and it didn't work. But a replacement was shipped quick and worked as expected.

The instructions were actually decent for this sort of thing, and there are videos online that walk through how to install it if you need more details. The installation only took a short time - easily less than 30 minutes. The main issue I ran into is that the double-sided tape it came with was barely sticky at all and didn't hold the black box unit to the frame like it was supposed to. And yes, I did clean/prep the surfaces. I ended up just using zip ties to attach it to an existing wiring harness near the same location, which worked fine. Also, the rubber dust cover that goes over the 4-prong plug is somewhat brittle. It is supposed to slip over the end of the plug so the cover doesn't fall off when not in use, but the rubber split easily when attempting to slide it over the plug. It's not a huge deal but was rather annoying. Other than those minor issues, everything went well with the install.

Needed one more 7.5A fuse to make it work. After that, no sweat. Works well.
