Many thanks to everyone for responding. Coincidentally I also got a response from Lydia which confirms Leigh's diagram - so thanks to all for a rapid response. I spent some time today trying to get the lift motors working but they are playing hard to get , plus I've only got main beam and no dip = so need to spend more time investigating. All fuses are intact so need to check the switch connections and relays. ( All the back lights are working ok)
