Expert Reply:
David, we don't have any t-connector style harness to hook up a 3rd brake light, but we do have the 3rd Brake Light Logic Module # PP20-702.
This module when hooked up will filter out any unwanted turn signal input so that the light only activate when brakes are applied.
I've attached a wiring diagram for you to check out as well.

Hey David, how did things go with the 3rd Brake Light Logic Module for your F-150 and Leer canopy? Your results could really help others trying to wire their dome or brake lights the same way.
