Re: 62 turn signal switch question

On that type of switch, the terminal that's up at the top / center should be connected to the wire that comes from the brake light switch.

On the next row down, the terminal on the left should be connected to the right rear brake / signal light. and the terminal on the right should go to the left rear brake / signal light.

On the bottom row, the terminal on the left should be connected to the right front turn signal as well as the right turn indicator in the dash. The middle terminal receives power from the turn signal flasher. And the right terminal goes to the left front turn signal and left indicator in the dash.

Note, the original '62 & '63 truck instrument clusters usually just had one spot for a turn signal indicator bulb that would flash for either direction. They accomplished that by connecting the left turn wire to one side of the bulb and the right turn wire to the other side (using a plastic socket to isolate both sides from ground). But you can convert over to separate left & right indicators by running each wire to a separate bulb with it's own ground.
