Thanks for all the kind comments.

As it happens I am currently putting together a shopping list for vehicle wiring products for the various bits I will need. If it is of use to people then I'm happy to post it up here.

Having a quick look at VWP now - I willprobably use the following -
battery to starter - 315/0.40 11.8mm OD, 300 Amp cable
Battery to megafuse - 315/0.40 11.8mm OD, 300 Amp cable

From the megafuse to the fuse/relay box I'm not quite sure what to do yet. If anyone has any ideas it would be much appreciated.
