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?

Yes, you can diode isolate them to keep them separate. You would tap each door wire and insert a diode between each and the door open input on the alarm. The line on the diode needs to be towards the alarm side.

Got to browsing some of the other threads... Would there be a down side to tapping this pink wire for the door trigger for the alarm?

Think it would be a little easier than soldering in diodes...

You'd have to try it with your particular alarm. Others have had issues with the alarm not liking the slow fade from ground to +12 when the doors are closed.
