Customer accessory circuit - is this one too?

I found the extra wiring under the passenger seat and added a usb charger, but at the battery I found wires marked the same. Not sure if it's the other end of the same wiring or a way to get a charger in the frunk. It's a 21 f3s

What you need is a cheap multimeter to figure that out. With no power applied you can use the "ohmmeter" portion of the meter to find out.

Simply make sure your ignition is in the off position and run your ohmmeter from point to point. If it is near zero ohms then the wires are joined.

I keep a test light for checking things like that. If the bulb doesn't light, there's no power or it's a ground wire.

On the F3T there are 3 customer accessory circuits.
1 in the Frunk, 1 under the Seat, 1 under the Service Panel on the left side of the bike.
Fuse location - Looking at the battery from the front of the Spyder with the frunk liner out, its the 6th mini fuse from the top left in the left hand fuse box. The fuse is 10 Amp so that would make it approximately 120 watts.
All 3 Accessory circuits share this same fuse and only receive power with engine running. Its no good for a battery tender.

I have my GPS, USB and 12V cig socket tied into the circuit under the left side panel. I plan to attach my Signature light to the circuit in the frunk.:thumbup:

It's best to install a fuse block for powering all electrical add ons. That way, you bypass the bike's fussy electronics. Mine is powered through a relay that is energized only when the ignition is on.
