K1100 Fuel gauge wiring
« on: December 08, 2024, 11:06:45 AM »
Hello everyone,

I am almost done with my custom wiring for my 1993 k1100LT using motogadget m unit.  I would like re-use existing fuel gauge to monitor my fuel level.
I am not sure what to do with gray/ blue wire.  Yellow goes to fuel gauge transmitter, brown is ground, green/black is 12v power? and do I need gray/ blue?
Clymer is missing fuel gauge for 1993 for some reason.  However, in 1994-and on the the gray/ blue goes to instrument light.  Plan is to use white wire from the fuel transmiter for the low fuel light, so the question remains what to do with the gray/ blue.  Do I need another light? Thanks.

Gray/blue is 12V+ for the backlight.
Once I had a Collie pup. Dug a hole and covered him up. Now I sit there by the hour. Waiting for a Collie-flower.
