Year of your truck would help - there have been a few changes now and then. In myu '95 the glow plug relay is under the mini-"hood" on top of the engine, passenger side front corner. You have to remove the mini-hood assembly to get to it.

The rear relay next to intake is the glow plug relay. The one in front by the fuel filter is for the air intake heater. The air intake heater helps to reduce smoke in colder weather. I believe it only functions after starting during cold weather when ambient temperature is 35 degrees or below. I removed the air intake heater coil to allow for unrestricted air flow, since where I live the temperature does not get that cold too much during the winter months. Does not seem have affected the warming up of the engine at all.
