amp turn on wire

[hellohi]

Hey there, I'm installing an aftermarket head unit, Panasonic 2007, into my 2002 Toyota Echo. The head unit's wire harness has an AMP TURN_ON (12V+) wire (blue/white) but the wire harness that mates with the car does not. What should I do/what will happen if I just insulate the tip of the wire?

(Likely unrelated, the wire harness that mates with the car has a DIMMER wire (orange/white) and the head unit's wire harness does not. My plan for now is to insulate the tip of the dimmer wire and leave it.)

Unless you plan on adding an amp later, I would add some more wire to it, coil it up and stash it somewhere so that next time you have it ready. Otherwise, if not, then cap it off and let her be.
