40HP 4-Stroke Mercury Remote Wiring Harness

[windyhill]

I have a 2013 Mercury 40HP 4-Stroke and I would like to know what the 5 extra wires with connectors on the Remote Control Harness are used for. The colors are Red, Green/WHT, Blue/WHT, Yellow/BLK and Tan/BLU. Could these be used to hook up a tachometer?

On my 2010 30 hp 4 stroke i found a connector added to the engine harness under the dash. It had the purple black and grey wires for the tach. But the grey wire changed to grey with red stripe.

I also have the plug for the 3rd tilt trim switch. Not sure why it's there.
