Review: Great Replacement Ford Trailer Plug. - Plug and play...hard to beat this for a Ford pickup. I have a 2000 F250, and this fit perfect with no problems at all. Works perfect. Great OEM replacement as the plug matches the factory plug perfect. If I could give it a 10, I would! Much less than the factory part, and this is in every way the same quality, perhaps OEM part?

Figuring it was time for a replacement, I found this. It was a perfect match for the factory harness under the driver-side rear bumper area. Unplugged the old one, plugged this one in and tested all the wiring to make sure it was correct and it all looks good. The old bracket didn't fit this, even after I tried drilling new holes. The old bracket simply wasn't wide enough. So I ordered a new bracket, and this one is a perfect fit - the holes in it align great with this harness: https://www.amazon.com/gp/product/B000BGM4IE That bracket comes with bolts/nuts and some self-tapping screws. I used the bolts and nuts to mount this harness, but I used some larger nuts and bolts I had lying around to mount the bracket to the truck, just to make sure it stayed put. I've had bad experiences with self-tapping screws rusting and falling out, and that'd be bad to have that happen on a mounting bracket for your trailer plug. Since this tow harness didn't come with any kind of nuts/bolts for attaching to a bracket, I'm glad the bracket came with them. I had a few I could have used but I wasn't sure they were stainless and probably wouldn't have worked. So just make sure whatever you use to mount this to your vehicle is some quality hardware, outdoor rated. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/16506755-tekonsha-118243-tow-custom-harness-7-way-compatible-with-1999](https://www.desertcart.vu/products/16506755-tekonsha-118243-tow-custom-harness-7-way-compatible-with-1999) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-16*
