I've scrubbed our forum and the interwebtrons high 'n' low and am coming up with scant info on the two rows of 12, female plug side pin functions for a 1993 K1100LT instrument cluster. They are slightly different from K75/K100 instruments, at least in my Big Block's wiring loom pulled from a late '93 K1100LT. The Clymer manual shows the K75/K100 pins and lists their functions, however, the K11 wiring schematics do not show pin functions. I am reading in many places that the instruments are 'all the same' (save the split plug type) but have determined that this is not the case. For example, my turn indicator pins are not the same as in any published K100 schematic. 
Ta.

There's always this plug 'n' play option at about USD$172 plus postage from Switzerland...

They're all the same except for Pins 12 & 14.

Pin 12:
K75/K100 - Choke indicator
K1/K100RS4V/93 K1100 - Unused
94+ K1100 - ABS indicator next to fuel warning indicator

Pin 14:
K75/K100 - BMU
K1/K100RS4V/93 K1100 - BMU & ABS
94+ K1100 - BMU

Hmmm, I'm getting a clear LH indicator signal from pin 7, RH indicator signal from pin 5, and high beam output from Pin 3.

In spite of this image.

This must be arid Ozian wit in action.

You have it backwards - probably comes from getting schooled in the upside down part of the world.

What you think is pin 7 is actually pin 19 and so on.

And whatever you posted has the speedo and tach pins reversed.

This shows all cluster pin arrangements:

Your diagramme is a good'un, all nicely detailed and such. I will check my work. I obtained the schematic image from the forum. It's hard to hang on up here at times. We get 'hammered' in the pub so we don't fall over.

high heels optional.
