[68 TT]

Your fuse box doesn't have the stock spots for them to plug into since it is pre-77 when it became an option but you can put the older glass fuse type terminal ends onto the pink, black & orange wires so they can plug into spots on your older fuse panel that were meant for accessories if there are any with a high enough amp rating.

You will need a fused power source that is constant on and one that is ignition on hot for the pink & orange wires and the black one can be grounded to the body under the dash with the other grounds to the left of the speedo. If I remember right the pink is the constant on power and the orange is ignition on hot.

The large plugs connect to the door component connectors where they come through the kick panel from the door.
