Hey Guys,
I'm the idiot who took his wiring harness apart and didnt make note of where each wire for the ignition switch goes... Thus far fiches have proved less then helpful so im hoping you guy can help out! See pics below.
My first issue. There are 5 positions on the ignition switch but only 4 are marked by a number (15,58, 30, 56)
There are 5 groupings of wires (also, im color blind so bare with me)
1 Red
1 Green + a lighter color
1 Green
1 Grey
1 with 2 light green + black wires in it
My guess is the Red goes to the lone 56. Beyond there im useless.

Note that the 3rd terminal (from the left, going across the 'top' row) is left unconnected-

The double-green wire connector is actually switched power for use with an accessory, such as a voltmeter. Otherwise, it is left unconnected.

Here's a diagram showing both Euro and US switch connections which should enable you to check the switch operation with a meter, buzzer or test light.
30 is Red +12 volt feed (either of the centre two connections)
15 is green feed to ignition circuit
58 is Grey Side lights
56 is Green/purple Headlight
Don't know about the Green/black wires but might be the brake light switch

A little late I guess, but here's the sketch I made whilst taking mine apart:

Bingo! Thanks a million!

An economical digital camera should be part of everyone's tool kit. Take multiple images from different angles prior to disassembly. You, too, could become a victim of the dreaded CRS affliction. Can't Remember S**t.
Having seen some terrible images created by cell phones, I wouldn't trust them for decent close ups.

You guys rock. thanks again. All the final parts are ordered. Painting tank, adding fluids and im finally ready to ride!

Just a follow up question, my switch has been drilled out and needs to be replaced. since stock is unobtanium, and i'm not using a stock mount a universal 3-poler seems to be the best replacement. in that case i would add the headlight and side lights to the accessory circuit? or is there a better replacement/method? here is a typical universal switch...
