I took the liberty of putting together a parts list from amazon for anyone interested this will make you a nice 4x6 plate set for just over $100. Sorry its single links i wasnt able to share the entire list. This is everything you need to build a plate set shy of a few fork terminals, wirenuts and a piece of SJOO 14/4 wire that you should be able to pick up at lowes or home depot or any hardware store really its just the black rubber extension cord lookin stuff. Dont get scared i can walk you through the whole build if need be.
