my own maplin version
switches, led's to show there on, and two in put cables one short for psu, one long for 12 volt on the floor!
deff more satisfying to make ur own and it was still cheaper than "alot more"!! and no where near the £34
one tip put a 30 amp or above what ever you use inline near your battery croc clips, being a motor tech un protected long wires melt quick and make a mess, a fuse near the battery/psu will blow on a dead short protecting burns damage etc
