Link to a smartcraft wiring diagram?????

[Alan762]

I purchased a SmartCraft engine monitor kit that seems to be incomplete. Does anyone know of a wiring diagram for these? I have the small square monitor, a short cable with a few single wires and a 20' cable. Both cables have female plugs on both ends. The "manual" only has user and calibration information, no wiring diagram. There must be something missing because there is no way to connect the cables together. 2015 Mercury Command Thrust 40 hp single engine installation.

Thanks,

You need the junction box for it. It connects to the cable from the engine and allows multiple gauges to be installed. In your case just one gauge but still need a box. This is for the tach and speedo but the same stuff.

Thank you!!!

That diagram is just what I needed. I can't believe it is not in the Mercury engine manual and it did not come with the gauge kit. I have been searching forums for a week trying to find a working link to it.

Thanks,

Again
