I would like to utilize the ACC switch on my road glide as a kill switch for amp i've installed in the saddle bag. I was wondering if there is a connector in the fairing or if the wires from the switch are easily accessible?

If I am not mistaken, the connector for ACC is under the seat.

If you want to make the connection at the connector under the seat, the parts needed are in this instruction sheet (use the parts for the end with a single connector):

The switched circuit uses the wire in chamber three of the four numbered chambers of the connector.

You can also tap/splice a wire at the switch itself at the fairing cap.

Good luck with your project.

Does your amp use a B+ signal to turn it on and off (internal relay)?
If so, that switch will be good.
If not, use that switch to activate a relay for the amp.

If you have other projects you can get an additional switch to fill in the blank.

A "B signal" I have no idea. The amp is the JL Audio XD400/4. It has a positive direct from the battery, a ground and a remote power. My thought was to control the remote power with a switch. I may be mistaken but I'm under the impression that the remote power does operate an internal switch in the amp. By killing that power I've shut off the amp and it is not drawing power from the battery.

I would assume the positive cable to the battery is fused?  It would really have to be...then the AUX switch should work fine, as it would just be operating a relay in the amp and not pulling too many amps for the fuse the AUX switch is attached to.

Been many many years since I've messed with this sort of thing, but wouldn't the ideal method be to trigger the amp from the radio so that it turns on automatically with the radio and turns off automatically with the radio?  No need for a separate switch, and remembering to turn it off or on, that way.

I would refrain from using main power for the amp via a switch.

The remote power is what needs to be switched, it is a low voltage input signal (usually from a head unit turn-on or from ACC on ignition switch). Unless the amp sees positive voltage on the remote turn-on it won't power up.

Good luck - should work out just fine by switching the remote power lead to the amp.

I would agree ... running remote power to switched ACC will only run the amp when keyed to ACC (or when bike is running). In order to do that, tap or splice-in the remote power-on lead to the wire on pin 12 of the 23-pin radio connector (J27). That is the "ACC Enable" lead.

However, OP asked for a method to install a "kill switch" (for whatever reason) - impling he wanted to kill the amp even when the bike was switched to ACC, or running.
To be able to kill the amp via an external switch, the low-voltage remote-on wire should be switched and not main battery.
