I had to do this 3 times on my 64. I ended up getting my switch from Dennis Carpenter for the swing away wheel and had to take the ends off and fish the wires thru with a piece of wire taped to the 4 or 5 wire harness. Pulled the fishing wire thru the column with a small stiff wire first. The first switch was an Ebay switch, unknown brand, then a Macs Auto switch, both of them defective. This job is un fun once. 3 times sucks.
