72 Wiring

[MikeandCheryl]

I'm going to re-wire my truck. i don't want to buy one of those kits - i want to modernize the whole system and reduce the number of circuits and fuses - perhaps similar to a race car which has the basics. I'm comfortable with the diagrams, and how everything goes together and I'm not that interested in having 15 different colours running will nilly. Has anyone out there done this and simplified the rat's nest of wiring and perhaps created a more simple flow of electrons? Further, one would need a source for all the different types of connectors, clips and such for each of the components. finally, there needs to be something to fit into the firewall connection that will allow the wiring to pass through into the cab.
Race cars seem to have unlimited money but they do have to start somewhere with a fuse/switch panel and a spool of wire.
Any suggestions?
thanks.
