Assume your changing out the '65s turn signal switch and it is stock. It is fairly straight forward. what I have always done is on the connector at the end of the wires from the switch, cut the the wires leaving enough wire to identify the color code. I also suggest picking up a tool to remove the pins out of the connector, makes life simple. after you've run the wiring down inside the column, and out the hole it is a fairly easy matter to match up the color codes to the correct location on the connector, just do them one at a time. Also a trick I have used for fishing the new wires down the column and out the hole is to tape the new wires to a stiff piece of straing wire and use that as a guide. I use small diameter welding wire. Don't forget to intaff the protective sleeve over the wires before you hook the wires to the connector
