    This product totally did the trick for my Ford SD replacement.

  2. RM

    This set comes with an RV plug. But hey, if you want, you can change it out with that fancy new Ford multi-plug that fits both the RV and flat 4 plugs. And the best part? It comes with all the necessary relays. Can you believe it? The dealer wanted $180 just for the wiring harness. This is totally a steal!

    Worked perfectly, no problems

  4. MP

    Cool product. But it wasn’t wired correctly for my 03 F350. I ended up having to swap the wires around.

  5. CF

    Worked like a dream with my 2001 F250. Just a heads up though, it doesn’t come with the extra wires for a four-pin connector. If that’s what you need, you might need to do a bit more searching.
