EZ Wiring is just as good IMO. Only difference people said they saw with both is EZ ships their kit in some plain crappy little box... Saw it in a mag too which was advertising for them but don't think they are just doing it to get you to buy the product, I hear it's true. That is what I plan to go with on my 48 and 66. I did the wiring on my headlights the other week and used heavier gauge wiring, new connectors, etc because on it the power goes to the headlight switch to the bright switch and THEN to the headlights, it losing power after going through the switches and so I put in relays and now the lights are MUCH brighter, I got rid of that old brittle wire. Only wires on the thing is the lights, gauges and that's probably it. So basically that ONE change was enough to do half of the wiring I had already haha.
