    Hello all,

    Looking for the best switched source on my 2017 Triumph T120 to tap into for a PDM60 power hub.

    Attached is a wiring schematic for the T120. The yellow wires seem to be the ignition switched. Looks like my options are:

    1) The yellow from the Brake/Tail Light that also runs to the Front Brake Switch and the Front Side/Running Light. This yellow originates directly at the ignition switch.

    2) The yellow from the USB Charging Point Connector (I assume this is the USB under the seat). This originates at the fuse box (fuse 9) and just goes to the USB Charging Point Connector.

    I am also replacing the OEM horn with an aftermarket one that draws more amps. I'll be supplying the new horn from the PDM60. That means that I won't be using the B/BL (blue/black) that supplies +12v switched to the horn. This B/BL is taking power from the yellow that runs into the Front Side/Running Light (number 1 above). As I will not be using this B/BL +12v to the horn, can I just extend that back with a spade connector extension to the PDM60 for switched power? Would save me from having to tap into the yellow somewhere else.

    Welcome to the family. Can't help with the wiring but one of the more sane inmates will be along soon i am sure. Do hit the upload a file button bottom right corner and show the bike to the inmate here.
