Ignition wiring

[bluebus69]

Hello out there,
Can anyone tell me where the light grey wire from the ignition switch should go. I have taken the broken switch out an replaced it with a new one but there was only a red, a red and black, and a black on the old switch, which I have reconnected and the engine turns over but wont start. I don’t know if this is to do with the light grey wire, or there is something else wrong.
Thanks
Bluebus
