GPS/Speedo Turbo Dynamics

[gpxsrx]

just purchased a GPS/Speedo gauge from Turbo dynamicss having install issues.
-red wire power off ignition
-Black ground
-White wire lighting but then there is a side note telling you to hook both white wires from gauge and inverter to light in speedo?
Never received inverter with gauge purchase not sure what’s up.
Emailed Ben @TD but I’m sure he is busy at Toronto show. Anyone have experience with gauge?
It’s for a 2015 SR Viper Hurrican Turbo. Thanks

Inverter must be for 2 strokes. What trouble are you having? The Photobucket pic does not show up.

All good Steve spoke to Ben @TD. The wiring diagram is wrong in the instructions and inverter is built into gauge, thanks

If anyone interested in this gauge installation connect wires as follow's :
_Connect red wire and white wire coming out of gauge together and connect the the red/vt wire coming out of the ignition switch.
_ connect Black wire to ground.
_Connect Black wire with Red tracer to the battery with a 1/4 amp fuse or 1 amp fuse.
