Misleading description(s)!
Only says once that they are 21ft & 4ft cables but multiple times that it is a 25ft & a 4ft cable - beware! Also the ground white wire is only 2ft long with an 1/8" eye, on the 21ft cable (not long enough for what I wanted). Other than that it is standard trailer wiring, the plug/socket are a snug fit & will be quite weather proof.

    5.0 out of 5 stars Trailer wiring kit, not an extension.
    Reviewed in Canada on April 17, 2024

    This is a perfectly good trailer wiring kit, not including lights obviously, but it is not an extension cable. Fortunately it looks like I will need this too, but the photos and wording imply it's an extension which it is not.

    The wire was a thicker gauge than what was installed previously. There was plenty of wire. I probably cut off 6 feet on each end. The jacket on the wire feels like it should last bumpy dirt roads and rubbing.

    Good quality materials and came with everything needed to replace a damaged wiring harness I had to replace. I only needed 9 feet so I had a lot of extra Length to work with. It was very easy to install and I would buy this again.
