Im converting my 88' F250's 351w to carb from EFI.Im not very mechanically knowledgeable so my friend is doing most the work. The EFI parts were taken off and left to rot in the bed. I already have the new manifold,distributor and the fuel pressure regulator. Also got headers, new plugs and wires. having a bit of trouble with the wiring tho. Am I missing anything. Any tip?
