The tailight wires come out of the hole to the right (in the picture) of the voltage regulator, and hook to the fuse box (small black rectangle). The ignition harness comes out of the hole to the left of the voltage regulator. The gas sender wire exits the bottom of the cab and re-enters with the harness to the right of the voltage regulator.

Are you making your own harness or using a pre-made one?
