I have a 1994 searay sundancer I just bought a promariner prosport 44021 to replace my original charger from 1994. However when I opened the box it had a normal 110 plug on it?? is this normal now? my old charger the wires get directly wired to the unit? What is the best way to go about making this work do i take the wires and put a outlet? I am just hesitant to do that because its in the engine bay and if that is what I am suppose to do is there a special type of outlet?
