Actually, I just looked at that site, where you got the picture from, and looked at the specs.

The DC750U has the dual posts, so that would be better for the winch setup. One setup would be for the stock cables, the other posts could be used to connect the winch. Just need to get the connectors for the GM style of posts, and you'd be all set up.

Otherwise, they appear to be exactly the same.

Sorry, I didn't catch that earlier.
