Whats the procedure for an 03 ???

 

if it's the same for the 1 & 2. then it's pretty easy, open hood, there's a bent wire, pull through the hole and turn bulb holder, put new bulb in. don't touch bulb! or , go to your local parts place(pep boys, auto zone), ask them to assist you, normally if they have someone to bs with and a chance to smoke a cigarette, they'll do it for free! done this with batteries, bulbs, you name it.

 

as billinohio said. thats as easy as can get.
Just a quick not. since you are replacing the bulb, try getting a hyper white bulb. looks great on the 03 head light units. the OEMs ate kinda yellowish.
I replaced both head lights and fog lights with hyper white bulbs. the front looks crispy at night.

 

From memory, the truck is in the shop. The grill has 3 screws on top, you loosen them, they are in a specialty fastener, the grill then pulls up and out, there isa small hinged plastic door hidinga screw in the lower inside of each assembly, take them out. There are two more screws on top of each assembly, remove them. Carefully pull out the assembly and the rest is super straight forward, just a simple clip holding the bulb in, replace with the hyperwhite, it's a nice improvement, looks factory, not blinding. Good luck, nothing to it.
