Welcome to the forum.
What year is your truck? Here are the wiring diagrams for 1985, other years should be similar:

See pages 70-80 for the exterior lights.
More details here showing how the circuits work, although this doesn't mention the wire colors:

All you need is a test light to test the wires you dont need wire colors.
I take it you are talking of the wires that run down the frame rail to the rear?
1 - wire is running lights
1 - is left turn / stop light
1 - is right turn / stop light
Now this last wire I think is back up lights but maybe a ground?
