Looking for LTR pin out info concerning Cherry Bomb

Hello all, my first post around here may or may not interest you..? I am looking to increase the performance of my King Quad 700. Being that it shares much in engine design and EFI with the R450, I am hoping someone may help with the pin out info on the diagnostic conector to which the Cherry Bomb plugs into...

This plug is the same on the King, has a total of 6 possible outputs, and only 4 are used. I am wondering if the King also has a "hidden" map that perhaps the CRBM or a 98.8 ohm resistor could put to use. So I need to know how many wires output to the R450 plug, and what voltages they produce with the key on and off. If you've read this far, thanks for bearing with... Perhaps we can benefit from each other in the performance game? A big bore LTR with 700 exhaust valves sure would move!

The GSX-R series roadbikes use gear position sensors (just a bank of resistors at the lever) to tell the ECU what gear it is in and by fooling it into thinking that it is in a certain gear by bridging the two wires with a certain value of resistance (usually 5th) people can get full power out of the bike.
Unfortunately it can also mess with the fueling in neutral as well but it does work well enough to do.
This probably has nothing to do with the cherrybomb wires though !
