I used quick splines rather than T taps for more cleaner wiring. I only used 4 of these, one to tap into the brake light wire up top at the harness, one to tap right side pillar brake light wire into left brake light pillar wire (since i connected left pillar and 3rd brake light directly with a spade connector) and 2 to connect a branch wire for the running lights to the licenses plate bulb grey wire (i used bullet connectors to connect the running light wires directly then tapped off of that)
