Every single wire are unique.
First you have to well locate ECU connector (E4 or E7 or E8 ). Unplugged those ECU connectors and pull the wire up (don't be too rough

)
Then within this connector, you have to locate the wire. You may help yourself locating the wire by isolating one and verify all the wires around if they are the same as the instruction says. There is several wire under there, some seems to be the same color but they aren't. Example : (red)...there is several red wire but some have white stripe on the side, all over it, some not. The key is to take your time and verify 2-3 times.
1) Locate the right ECU connector
2) Within this connector, locate right wire, use the "neighbor" wire
3) Double-check to be sure it is exactly it...clip the 3M connector in.
Good success !
