Its for the HPCA (cold start) sensor. It is only used on the mechanical DB2 IP's. It has two spade connectors.

David, on a 96 you wouldn't think you should have
electrical plugs for that location. I guess that's what you're talking about. Maybe pipe plug huh!!

Actually on 92-93 6.5's the HPCA switch is in the crossover. Refer to Buffalo Guy's past posts "mystery wire" The plug in the right side head
was for the glow plug controller inhibit switch. which was moved to the controller. Mine just has a pipe plug in that location. Refer to the troubleshooting guide, 93 and earlier glow plugs for info for the inhibit switch.
IIRC it states it was used somewhere in 84 and then discontinued because it was not reliable.
