Hi.
Just been looking around our 2013 cfmoto z800.
Under the drivers seat there is a lid with 2 Philips screws, im assuming it's where the battery used to live.
I found a small rectangular device that has a wire going to a long thin thing that's stuck to the heel board and 3 wires, yellow (no idea) black (earth) and red (power) although the red is not connected to the battery.
I'm thinking it's maybe a GPS? Any help would be appreciated.

From the factory, the farthest rear compartment has the main fuse and holder and if the unit has P/S, the motor fuse and holder. That's it. Anything else was added later by the dealer or owner. The next closed compartment forward is for a second battery and the open one next is just storage. I keep my tow strap in it.

Cheers NMKawierider.
I'll royally ask tge previous owner what it is, must have been fitted by a real professional, blue scotch blocks!
