I was given a 2007.5 GMC 2500hd 2WD.
I had to replace the heads. As I’m putting it back together. I got stuck on this cable for the glow plug module. Where do I bolt in the other end? (This is my first time working on a Diesel)

I believe that goes to the grid heater. Glad your willing to learn and do your own work. Good luck.

On second thought can you provide a pic that gives a broader view? Is which end of which wire? It might go over into fuse box if it is the actual glow plug module wire.

Ok just to make sure you said you have a 2007.5 which would indicate its an LMM but the pic looks like an LBZ.

Yep that is for the grid heater. Your truck is the early 2007 or classic the way it looks. The picture I attached earlier is of an LMM but is very similar and attaches under a cover on top.
