Amazon.com had these things for almost half of what you'd pay in an RV shop. Think it was around $85. 00. You should be able to find it pretty easy. Be at your house in a few days.
Also, it comes with a wire harness that you splice to the pig-tail that came with your truck. But I'd get a pre-made one that Tekonsha also makes. When I got my unit at an RV store I went ahead and purchased the Tekonsha made wire harness also. It's sold separately and should be on the store shelf near the controller. It's cheap, done well, heavy duty wires, has a braided mesh around the wires that looks real nice, and plugs right into your truck socket with no splicing.
Lastly, Tekonsha updated this unit about a year ago with 2. 4 software (something like that). There's still some old units out there. Just look on the bottom of the box and make sure it's got the 2. 4 sticker on it. Or the online store will indicate this also. The update was only to deal was some crudy Ford problem. But I always like to get the updated equipment.
The unit is very good. Some here may speak of the Jordan controller also. But I can't imagine anything better then this Prodigy. Felt like my truck wasn't even hooked to the trailer anymore. Like driving a car. The unit is highly intelligent.
And the quick disconnect lets me put the unit in the house when I'm not using it for months at a time. I don't think you can do that with the Jordan very easily. But someone can correct me about that.
