Well im sure you saw the labels on the coils. As for the motor L1 is the front housing more towards the front bumper and L2 is the rear housing toward dash. However those are in theory totally interchangeable since the 2 leading plugs fire at the exact same time thats why they are on the same coil with the same electrical connection. I like to think of leading as lower and trailing as top if I ever get those confused. And the bur9eq plug is the colder trailing one commonly used for all 4. Also make sure you get the coil harness connections right white black blue is the order from left to right, thats critical.
