quick headlight question

[steverino66]

I'm trying to get headlights/taillights going for the first time - dash light switch is new, verified all the bulbs are good in another vehicle but can't get the lights to come on. I have the hood off, so no parking lights hooked up in front; just spliced in plug for tilt steering column but the column is still out of truck. Am I missing a basic connection with those pieces out (I checked all the light plugs and grounds but haven't chased any voltage in the wires)?
