Left side handlebar switch question?

Old switch has Orange/White stripe & Blue/White stripe some colours are hard to guess due to fading.
I was just worried if they changed the way the switches work between K1 & K2 versions. Looks like I will have to do some testing with my AVO meter.

Good to hear the looms are the same as the loom was in pretty good condition generally, just had to re-tape some parts & fit new connector blocks.
The extra wire unaccounted for could be a different horn wiring arrangement.
Bryanj:
Early horns had 1 wire that grounded to bars like starter button, later ones had2 wires and sent power to the horn, you need to know which sort as the wiring at the horn is different
Early has black power then wire to switch
Later has wire from switch and a loop to ground

It can be confusing with differences between US UK Europe specs, the type with hi/lo on left is more like 550 and means the rh has to have off/park/headlamp positions. There will be differences from the wiring diagram i sent you, I find its easier to draw out the seperate circuits to make it easier.

I have the right side handlebar switch with the three positions off/P/H looks similar to my 400.
Oddly enough I have been drawing diagrams to show the switch connections as you have suggested, I printed off the B&W diagram you sent me as an aid.
I suspect some of my problems are with faded wiring colours making light blue & grey look similar.
I've done an XL sheet showing all the wires that go into the headlamp from the main loom denoting male or female connectors and what I think the colours are.
On my 400 I did a similar exercise to match up the connections. I would sooner spend time trying it out on paper than burning out a new switch or short a loom.
Not helped by my aftermarket switches having some different colours to boot. I need to re-learn my AVO meter skills on U-tube. 8) 8) 8)
