Dave, Relay deffo works. Hadn't noticed the single pin being a bit shoogly but the other one had a bit of a rattle from inside and although worked I wasn't wanting to give you that one.

I've had a look at my wiring tonight for you. tried to take a pic but not easily accessible. so here goes

Pin 30 :- Thick red wire (Live Feed)
Pin 1 :- Thin green wire with either a red or orange (couldn't make out clearly)stripe running down it
Pin 87 :- 2 thin black wires with red stripe
Pin 15 :- 1 thin solid black wire and also 1 thin black with green stripe
Pin 31 :- Brown (Earth)

Pin 50 :- has a small single black plug with a thin black wire with yellow stripe


Hope this helps mate
