Good. Remember - I didn't write the service manual. I've also seen a few wires in the wiring section that the colors were screwed up for, so I typically also don't trust it, and figure out with my test light or multi-meter.
Sorry - I didn't bother to pull out from my parts box the spare, and check that one out for you. But should be easy with it disconnected to find the "hot wire", then one of the other big ones should turn on stuff like the dashboard lights, and the other bigger wire should engage the starter.
