Ignition Switch Wiring

Hi there,

Looking at the old ignition switch:




Im trying to work out which wires go where on the new one:







Im guessing White is IGN (Ignition)?

Light Green/White is ST (starter)?

Brown is BAT (Battery)?

Red/White is ACC?



Thanks

Assuming standard Lucas scheme

Brown main battery feed, unfused
White +Red Solenoid starter switch to starter
White Ignition control circuit

The White + Green should be the fuel pump circuit.

Connect the other and see what doesn't work then you will know.
