Fuel gauge terminal "I"

Bought a used FD226. Purple wire on fuel gauge not hooked up and can not find where it goes. Can it be connected to 12vdc with a switch to turn on and off.

    You probably already got the answer for this, but I figured I would put this up for others for the future.

    Here's a diagram that should help you in wire identification along with the ABYC wiring standard.
