Joe,
This maker might interest you more. Theirs is truly "plug and play" and unlike the Dinan, does not require any cutting into the wire loom for the 12vt power source.
Also, you can order it preprogrammed with different default settings than what Dinan offers. Dinan appears to be default in the "automatic" factory mode, and then press the button to open.
This offers various modes of operation when in default and when you press the button, but you have to order it the way you want it, and it cannot be changed after ordering. Automatic default and open when the button is pressed like the Dinan is probably most popular, but it does give you other options.

Construction looks good as well. Pricing is competitive. I have not yet tried the product, or know anyone that has. And word of warning, their tech support is non existent. I emailed them a couple times in the past two months with no response.
