I am planning on building a lowcost and was browsing the forums. I see a bunch of questions on what to use for a wiring it. I have built a Triumph TR6 and rewired it w/ a Classic Technologies fuse box. The fuse box was so nicely laid out and it had all the circuits and relays I wanted and needed to rewire my car. The fuse box is like 2 1/2 X 4 X 6 and it has 13 fuses, a horn relay, high and low beam relays, hazard flasher relay, signal flasher, ignition, starter and accessory power relays. Its really nice it has everything. Plus you get color coded wire, a nice color electrical schematic, instructions and more. I will definitely use it again when I do my lowcost. Here is a picture of it.
