Your remote wire is switched by the head unit. The accessory wire is switched with the ignition usually, but I have seen accessory wires that were not switched in random vehicles. Some accessory wires are constant. You need a DMM to probe and see how yours works in your particular vehicle.
both answers correct good job guys this is what I like to see here.Your acc wire is fused and can power several things (radar det, cellphone charger, etc.).
The remote wire is not fused and has extremely low power and should only be used to connect to amps.
Don't get how your computer has a remote wire?Well I'm powering my Amp with a remote wire from my computer. But my computer also has a ACC wire that needs power, can I power my comp using my spare remote wire that i have ran or do u think i need to have a "real" acc?
