Digital speedometer and fuel managment gauge wiring

[Boatdoctor]

You have two choices, inthe middle of the gauge power harness(one between ignition switch and gauges) you will see a short blue wire and a yellow wire. If you connect the blue wire to yellow wire backlight in gauges will come on when turn ignition key on. If you connect the blue wire to navigation light switch in boat the backlights will come on when turn boat lights on. DO NOT connect blue wire to both key switch and boat light switch, check all blue wire connections at gauges first to make nothing but gauges are connected to blue wires.
Here is guides on them

digital speedometer wiring

I emailed it to you.

I purchased a digital speedometer (6Y5-83570-S5) and need to connect it to my fuel tank. I have the digital tachometer mounted next to it. Can you send me the wiring diagram for this to dfdavis98@yahoo.com I am trying to assist with the oil spill clean-up tomorrow.

Thanks,
