I used Ron Francis wiring. Nice quality. great fusebox. not all wiring is included... no steeringcolumn, no wiper, heater, gauges. comes with a gm style headlightswitch. All that was no problem for me since I dont use any of the old gauges or switches, except for the 3-speed wiper... that one is little difficult to replace. The bulkhead connector is replaced by a piece of metal with 2 grommets for wires. You need to drill 4 holes for that part, or fabricate a plate to fit the bulkhead hole. Not a 1 days job, but overall ,I like it
