20mm holes were drilled in the under dash trays near to the heater outlets. The switch wires were disconnected from the loom and fed through the tray and clicked in to place. They were then reconnected to the looms.
So now to test. Without the ignition switched on, there were no lights on the switches in any position - so a good start! Next the ignition was turned on. A green light when the switch was set to the low setting. A red light when it was set to maximum. And no light at the off/central point - great news.
Now I just need to test it in anger.
Edit: Been out in the car today (Thursday) and the heated seats really work. Brilliant!
