Unit is compact. Terminal nuts aren't captured and it's possible to unscrew the terminals too far so it can be tricky if wire size is large but it's easy to restart the nuts. The wiring diagram on the back of the unit is a little misleading to the uninitiated. It appears there is no + or - polarity on the inputs so it can be wired either way and it still operates. The output is a basic switched positive so you need to loop the positive wire from the input terminal across. would be better if it had an internal circuit instead of having to have an additional external wire. Note that some other advertised units have the updated wiring diagram.
