Im no wiring guru, but I did the conversion in my 63. I used a new wiring harness due to the condition of my OEM harness, but I did research on it before. There are some things that'll change, and some remain the same. The fuel guage is the same. The oil pressure guage will have to be plumbed from the block, and the wires for the sender can be eliminated. The ammeter or voltmeter depending on what you have will have to be wired. And the temp sending unit has to be swapped out and wired. The speedometer is the same as is the turn signals and the cluster bulbs. Tachs had their own wiring harness, so it's completely seperate.
