I believe it is the gray wire out of the smaller ECU plug? I am installing a McCruise on my 2013 so I figured a nice time to install a gear indicator light. For reference I am going positive and ground to switchable power control 8. Speed sensor of the blue wire out of large ECU plug (with McCruise I am using the return blue wire). The Healtech image is hard to decipher, and I do not have a wiring diagram. If you have your bike torn down and want an item some feel is worthless knowing the correct wires makes a Gear Indicator a fairly easy install.
