How Many Glow Plug Relays???

I've got a 2002 7.3 and I know I have a glow plug relay that has gone bad. However, there are two relays that look identical almost side by side. I know one is for glow plugs but what is the other one for? Is it a separate system or or there glow plug relays for each side of the block???

The other one is for your AIH (Air Inlet Heater) that is mounted in your intake spyder. Think of a heater element that glows red hot to help warm the air coming in the motor on cold start ups.

It's the shorter one in the back.

Also, the AIH has nothing to do with starting in the cold. In fact, your engine has to be running for a min or two for it to even activate (which it does RARELY anyway).
