2014 F150 Install Assistance for Parking Light

Question

I have a FOR1 T-harness and EVO-ALL and I'm trying to wire it up for the first time. I'm using page 6 of this document as my guide. https://www.wirecolor.com/download/94891/94891.pdf

I've tapped into BCM Passenger Kick Panel for Parking Light+, but I'm not sure what to do with this wire. Am I expected to bring my own relay? Do I double up the wire on the existing factory relay and then run a wire from the factory relay to EVO-ALL? I've never tapped into a relay, do people just pop it out and put wire alongside the pin as the put it back in or is there a way to use a posi-tap on the back side easily?
