Gear indicator is complete. Pic Heavy and Video!

[Yev]

What part did you use for the gear switch? Was it the 37720-45100?
I have one I was going to use to program a PIC processor but if the switch is what you used, then I'd be interested in buying one of your boards and save me some work.
By the way, if you want any help, I have done schematic through completed PC board and could help you make more boards or add more functionality with PIC processors (I've done parts for AMF/Brunswick pinsetters and for pipe organ interfacing and MIDI controllers with PICs. Other stuff with Z-80's and Parallax SX's).

Yes we used that part #.
My friend is the one that does all the electrical engineering parts of this project.
I can see what a fair price for everything but the switch is. I will shoot you a PM with an update.
Thanks,
Yev

I have a 2007 GS500f. When I looked at the neutral indicator switch it has 3 wires rather than the single blue wire I was expecting. The GS500f wiring diagram has the additional 2 (GR/BL & R/B) wires going to the igniter. If I were to install the 37720-45100 switch what happens to the two wires going to the igniter. Do they matter?

Cheers

Rob,
I am at work right now so I can't verify any diagrams..
But from the top of my head I believe there is one wire that is not used.
I have the indicator installed on my 2007 GS500e (used to be an F) and everything works great!
Hope that helps, if not send me a PM or post up again and I will verify when I get home.

It is kinda cute, but not for the trouble and expense.

Same can be said about any modification.

To each their own!

Cheers Yev.

Here are the two wire I'm talking about. This is from the K4 service manual supplement. Do you know what they are connected to in the switch, and if they are needed.

I did check my bike and that harness plug was left unplugged and tucked away. It is not necessary for the operation of the bike when you switch over to our gear indicator.
Hope that helps!

It would be interesting to look into the switch itself and actually see where those wires go and what they do. OR use an ohm meter and check resistance with the switch on as you change gears. Maybe it is a resistor that changes value with the gear and slightly changes the ignition timing.

I'll check on my 2009 model next week. I'm getting the gear indicator so when I install it, I'll see if my GS has the same thing and if so, I'll determine what it does.

Here is the harness that is probably in question:

I do have it unplugged and have done almost 4K miles without it plugged in with no problems.
I just tucked it away when I installed the gear indicator:

That would be great!  
And a big thanks for being the first buyer.  
Here is yours... all ready to be shipped:

Bump.. got one all set for sale..

So what is the mystery wire?

So what is the mystery wire?

The pic above was for a fellow GS member who had his own gear switch.
For everyone else it would come with no "mystery wires".
It would come as a plug and play.
