on the 5 wire plug to the icm, what happens to the center ground (larger brown wire). its been a while since i did the 2.0 coil pack swap and i cant remember where this wire goes or if it gets pulled. i want to say it also got pulled but im not 100% sure.

the 4 wire plug are the wires that run to the coil packs and they get removed completely. The 4 super small wires on the 5 wire side run straight to there respective coils. Is that 5th wire grounded on the back of the head?
