thanks for the advice re my morgan 4/4, however, I bought the Lucas toggle switches from Newark auto-jumble about 4 years ago and I'm just getting round to replace the current switches. I am putting the original dashboard back (fed up with wood) having bought a centre panel from Melvyn about 5 years ago.(things move at a slower pace in Liverpool) The problem I have is the heater and light switches, which wire goes where? the back of the switch has 6 spade terminals and there are 3 wires coming from the loom. the heater is 2 speed. Do I need to put a relay between the loom and the switch? The Retro Sound radio I will fit in the dash.As before any suggestions will be most appreciated.
