It is clear for me that the lengthiest wire is the one that goes to the ECM (ECM pin 40-D3 connector).
One of the two short wires you sent me is for ground and there's another one that I don't know what it is for.

It's not been clear to me on vince87's DIY pdf all things related to D3 connector, One wire to the ECM, but about the other two, where do I plug the wires that connect in D3 ( the other end of the wires), if one is ground, what about the other. The small one that is not ground go from where to where?

Sorry if am asking dumb questions I just want to do this right.
