A little off topic, but are there any books that cover basic race car building? That would answer wiring questions and such. Seems most racers, even seasoned ones, have many different methods to builds.

The book I use the most is the cheque book!

If you use your standard 30 amp relay and spade connectors, you might want to squeeze them a bit with pliers. I've seen them melt and burn up at that point.

Good heavy duty switches are hard to come by. Stop by your local small engine repair shop and have them order you some chain saw switches...chances are they won't have any in stock because they never fail. They will utilize a screw terminal instead of spade connectors.

!0-4 on the relays...make a world of difference. Quality stuff here... http://www.leashelectronics.com/
