Kawasaki Z1000 K1 LTD Ignition Switch Replacement
Posted: Thu Nov 13, 2025 8:20 pm
Hi
I had an issue with the ignition switch on my LTD - basically it started jamming so it couldn't be turned with the key without considerable force. I managed to source a replacement which has the exact same dimensions as the original, so it fits in the top yoke, but the wiring colours are different - it's for a Kawasaki Vulcan 750. Z-Power sell these switches but they don't know what wires I need to connect to make it work properly.
On the original Z1000 switch I have 6 wires in the multi block connector (black/white, orange/white, brown, red, white, orange) and a yellow/orange bullet connector.
On the vulcan 750 switch I have 5 wires in the multi block (blue, yellow, orange/white, red, black/white) and 2 bullet connectors - one white and one brown/white.
The multi block on the Vulcan 750 switch is a completely different size so I cut it off and replaced the connectors with 6.3mm ones.
I've connected the wires from the new switch to the multi block in the headlight in a variety of positions and the best scenario I can get is , power to starter, lights, indicators - no oil light or neutral lights. Brake lights only work when the lights are switched on.
I've read a few forum posts on this subject but there aren't any conclusive answers from what I can see.
If anyone is able to shed any light on to which colours on the new switch connect to which colours on the Z1000 multi block in the headlight I’d be much obliged as I'm no wiring expert and even less of an expert on reading wiring diagrams
thanks
Billy
