Just want to endorse Vehicle Wiring Products.They are in Ilkeston,Derbyshire.I used to work about 100 yds.away from their works and I have to say they are one of the best companies we ever dealt with for ANYTHING to do with fittings,wiring,relays,pipework,tools,etc,etc.Have a look on-line,they will send you a catalogue in the post also.So knowledgable and helpful.
I must add I have no tie up with them at all, we were just very satisfied customers.
