Does your truck still have the external regulator type alternator? That harness plug appears to be the one that should be plugged into the regulator on your radiator core support but has jumpers that indicate an internally regulated alternator. This wiring diagram may be prove useful. I also found that another member has posted a complete wiring diagram at http://67-72chevytrucks.com/vboard/s...d.php?t=378552 Hope this helps
