One thing to remember about this harness and most others, they usually do not supply any of the extra ground wiring needed. So remember to include them in your harness runs before taping up your harness.

Dash and interior lighting, and the door switches are usually negative triggers.

So the harness will may supply power to a bulb, but the other side maybe a cable run to a door switch or dash with which then grounds when the circuit is closed.

This is also true of things like the horn button which is a ground trigger.
