You may need to enlarge the pic to see my drawing on it.
The 12 volt supply to the rallye panel is at approx 9 o'clock on the round harness connecter. It goes to the limiter in the fuel gauge and nowhere else. Thats the odd thing about a rallye panel , If the gauges dont respond to switch on you dont know if its live or not. Not one indicater lamp or anything else to look for.
