Is accessory power the cigarette lighter?

So according to the manual, the accessory power fuse is a 20 amp fuse. This powers the cig lighter and the 2 usb connectors in the center console correct?

I'm asking because im looking for what I should tap in to for a boost gauge. I've looked around and it never really says what exactly they tapped in to for power. Obviously it would make the most sense to tap in to the headlight since the only time I would need light is when the lights are on. But is it wise to run an add-a-fuse line to something as crucial as the headlights?

Any input would be great. Thanks again guys.
