Question:

my old actuator has one blue wire, the new one i have on order has one blue wire and one white wire, which one should be wired to the vehicle reverse lights ?

Reverse lock out solenoids are not polarity sensitive so you could run either the white or the blue wire of the Dexter coupler part # DX99FR as the power or ground and you'd be totally fine.

So... One of the two wires is a power and the other is a ground and you are says it doesn't matter which one you use for the power or the ground? In a normal world the blue would be the power and the white would be the ground correct. They both need to be hooked up? The old unit only had a blue wire.

@JaredD Yes, it doesn't matter which you choose as power or ground as it's not polarity sensitive. You are correct normally white is ground though. Your old setup grounded through it's mounting hardware which is why there was only one wire.
