So it looks like the '65 M&H harness is just going to plug and play under the hood of the '63! To match I used the '65 dash harness but that has the fuse box on the LH side of the column and '65 and up they did not have push button so that was fine... I may need to make a bracket or modify that harness. I wish they made a '63 specific but they don't and the '64's were all backordered and I did not know how long it would be.... Now to call M&H and see if they can make a factory positive battery cable...
Reconditioned wiring clips with Plastidip. There are small cutouts where these go, if you don't use them the clips wont snap on worth beans.
