Stupid Question Coming.....
I have a '99 F-350 with the 7.3L. Are there 2 Glow Plug Relays or only 1? Is a Glow Plug Relay the same as a Glow Plug Controller?

I'm not sure on the SD's, but there should only be one relay. A glow plug controller is like th ones on old 7.3 IDI, that is a relay and has a circuit to control the length of time the glow plugs are on. In the newer trucks, the glow plugs are controlled by the PCM.

1 relay, no controller.

Pics
Here is a pic of the items in question. In the pic, left would be towards the cab and right is towards the front (grill). Are they both glow plug relays? If not, which one is, and what is the other one?

The relay with the brown wire and the yellow wire on the same terminal is your glow plug relay. The other relay is the manifold air heater relay. Not sure which is on the left or right. I can't see the wires going to the relay.

I thought the other one was a starter relay?
