Fleetwood arcadia power lift wiring help needed

Ok heard back from tHe place I bought tHe current limiter from (Midland RV). They advised that the unit is set up like a standard 12v device, so red is +. And black is negative. Hooking it up to the fleetwood then means that black from the trailer goes to red on the current limiter and white goes to black. I hooked it up and it seems to work. I'll post back if it inexplicitidly craps out....
