No need to
fear A.C. wiring. Respect, yes. Fear, no.
That power inlet uses QDs, just like buttons do.
Heat shrink is a nice touch if you have a heat gun and don't mind the effort:
* Pull one QD at a time.
* Place heat shrink on the wire, but don't shrink it yet.
* Reattach the QD.
* If you're paranoid about whether you messed up the wiring, check the resistance on the hot, neutral, and ground wires from the plug that normally plugs into the wall outlet to a power strip outlet inside the cab.
* Once all the heat shrink pieces are in place, fire up the heat gun and shrink 'em on down.
