so my buddies dad bought a 6.9 to replace a 7.3 that had scored the cylinders and this is somehow tied into the Gp harness. i've never seen one before, is something he needs or should he just cap it off when he puts the 7.3 Gp system on?
early glow plug controller(6.9 type)
run away from it as fast as possible.
your 7.3 glow plug stuff is a bolt- in. just put a pipe plug where the controller is at or leave it there and ignore it.
