That is strange. Since the "WOW" test shows you do have the LED and it is wired your more than 1/2 way there. It seems to imply all your missing is the firmware/software in the ECM in order for it to work.
That 6th speed light is not turned on with a simple gear position transmission switch. The ECM knows the ground speed of the bike by the Vehicle Speed sensor (VSS). It also knows the engine RPM through the crank sensor. Therefore as long as the clutch is engaged, when the ECM sees the "proper match" of ground speed vs RPM, it determines you MUST be in 6th speed. Example=> 2250 RPM with a ground speed of 70 MPH is a proper match so you must be in 6th. At that time, the ECM sends serial data over the bus to tell the speedo to turn on the 6th speed light. The speedo now slaves that command and turns on the light.
(Hence the reason I asked about the primary sprocket change. By doing that you would loose the possible "match" combination)
Now if your clutch lever switch was bad and was not telling the ECM that you were "coupled", the light just may not come on. I am not sure if the speedo disregards "matches" if the clutch lever switch is not closed. Probably does in order to prevent the 6th gear light from blinking since you will have "matches" for split seconds as you shift different gears .
Now,, that same clutch lever switch allows you to start the bike when it is in gear as long as the clutch lever is pulled in. You may want to perform that simple test to see if the switch is communicating with the ECM.
If you find that the clutch lever switch is working, I would then say the software in the ECM is missing.
Who knows,, just a theory.
