Kawasaki Z1000 K1 LTD Ignition Switch Replacement

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 form 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

You have a couple of options, it appears that your problem is mechanical so below is a link to a tutorial I wrote on how the repair the ignition lock.

If you want to fit the new unit complete below is how (I believe you could have just swopped the original electrical switch onto the new lock)

Thank you @Wookie58  I'll have a read through your tutorial but I think that would be my last resort. Plugging the new switch in is the ideal solution so I'll check the colours of new against old and see where i get to.
Thanks for your quick response.

 

Have you taken the stock switch apart, cleaned and reassembled with fresh dielectric grease?
Many times the original grease is hardened and causes issues.
