My 2011 Elddis 180 has a basic manual step. I bought the van last year and when taking a look underneath noticed that there is a push button switch that is operated when the step is closed. There is a bundle of wire attatched to the switch but its not connected to anything. I assume this is for a " step left down " alarm. Two questions: was this ever fitted as standard? and if so how would I go about reconnecting it? I drove half way to Devon with the step down in April. So this might be useful.
