Installation of Pacer Performance 3rd Brake Light Logic Module on Truck Topper

Question:

Have a 2018 F150. Have a cap topper and need to wire the CHMSL. Do I need to splice into both top and bottom stop light and turn signal wires to wire into the yellow wire. Tried just one circuit and when the turn signal is activated the CHMSL flashes. Can you clarify exactly which wires to tap into. These are halogen bulbs with dual filament.

When installing the Pacer Performance 3rd Brake Light Module # PP20-702 you will need to connect the yellow wires to both the right and left turn signal (one signal to each wire), and then the green wire will wire into your 3rd brake light on your truck topper. This module can be used on either LED or incandescent bulbs.
