What am I overlooking here.

[rs74]

I am revamping under the dash from all the previous people having there hands in there. Currently working on the cluster on my diesel K30. I have three lights left to plug in but only have homes for two of them. Does one of these go to the cluster. All the holes have the twist in bulbs with no wires running to them. One set is the glow plug light and the other is the fuel in water light. Not sure about the one that has a gray wire and pink with black stripe on it. Trying to figure out what this light is. Alot of these lights were unplugged when I tore into it or missing so I am trying to make it right.
