I’ve just purchased several electrical items off this excellent firm. All the parts arrived next day delivery along with a catalogue. A brilliant selection of stuff at keen prices. Highly recommended.

Yep, used them many times.
+1 for VWP
Most of the wire for my new loom came from them, including the battery cables and connectors.
