I was going to go outside and scan codes just for shits when I realized that my check engine light does not turn on for a test when I turn my key on. Isn't it supposed to? Burned out bulb perhaps?

Yes......if you turn the key to the run position without starting the truck, the CEL *should* light......and then after you start it the light should go off.

If you have no CEL at initial start up the bulb is burnt out or is missing.

Steve, I already had the cluster removed before I saw your post. Unfortunately for me, the bulb is in working order. What's my next move?

Additionally, what is the FUEL RESET light for in the dash? Does it light when the inertia switch is tripped?

I don't understand what I'm supposed to be connecting on the DLC. What should pin should I be connecting to the battery + through a test light?

I put the cluster back in and now it works. Weird. Now, I also found out what that STO-looking harness inside the cab is...my chime pigtail and the box was in the glovebox from the PO. Thought it was a brake controller or something. :D
