Which harness to use for analog gauges

[steve45]

I working on a 2014 Mercury 40 HP 4 stroke. Model number 1A40303BZ Serial number is 1c292953 I have rigged it on a boat with side mount remote control box 881170a14 . The control works great and the motor runs fine but Im having trouble finding the harness that works with the plug in provided on the control that would hook up to analog gauges. The plug in on the control is about 1 1/2 wide and rectangular in shape and has either 8 or 10 wires. Thanks for your help.
