Those two wires are actually tied together as a single input into the ECM, so you probably only need the yellow and that is probably the reason for the lacking blue.

Identified all of the wires and confirmed they are the right ones! Thanks for your continued help! However, they have proven difficult to tap because of the little slack in the harness.

So...I am going to have to connect all the door and truck triggers together. Got to thinking though, when I do this - the Driver Info Center is going to show all doors opened when only one actually is...

Do you know if I could place a diode in line with each of the taps before I tie them together to prevent the problem caused by just tying them all together - to maintain the integrity of each circuit? Will a diode pass the negative/ground provided by the switching?
