Good evening. I am trying to completely rewire a series 2a from 1965. I have bought a new loom from Autosparks and am trying to fit it. All has gone well except for two areas. I cant work out which wires go where on the ignition switch... the diagram is coded with letters IGN, A, S, H, and the switch with numbers! Also cant see how to get the lights to work. On a series the light switch seems to be on the key switch? Is that correct? Can someone tell me how the lights work on a 2a.. (new to me this old stuff... I do defenders!)... Is it 1 click to turn on power to start and one more for lights?
