Default 95 k2500 glow plug relay wiring

Hey guys, my glow system quit working a couple days ago and I got dtc 29 for glow relay fault so I replaced it. New unit still does not work, no clicking no light, nothing. Red wire is hot, pink and yellow wires are dead, and black seems to be ground (small black) any ideas? I've checked the glow plug fuse and the guages fuse, as the chilton diagram shows it on the pink wire circuit... thanks in advance!
