tail light wiring diagram

[skamionek]

My son bought a 2017 Silverware and wanted a set of lighted step Inserts for a gift.  We bought them for him and trying to wire them.  They have led lights for running, reverse and braking.  Before I cut into wiring harness I see three wires to each of the tail light bulbs.  the wire colors don't match the step lights wiring. Does any one have an idea of what to splice ?

Green wire is the turn signal. Black is ground. Brown is park lamp...if I recall.

Running light/park lamp = same.

You should have a separate bulb socket for the the reverse bulb.

The two black are most likely tied together.

Had hard time getting my light bar wired up and working tapping the factory wiring. So I bought one of these Curt harness. In less than half the time I spent trying to figure it out I had it done with this. Just cut 5 way plug off.
