The main question here is, while driving on a bumpy and/or winding road and monitoring the live data with your scanner, do all 4 dampers appearing to fluctuate on their own, particularly right versus left, as apposed to all 4 fluctuating in exactly the same manner at the same time?
Do you have a tow/haul mode on your truck, if yes, how to the actuators fluctuate in that mode?
As luck would have it, my second order of a set of electrical connector shells arrived on one day, and the original 'lost' order of a set of electrical connector shells arrived the following day. So, I ended up with 140 electrical connector shells, when I only needed 2. But, at least I had what I needed. I assembled the pigtail assemblies needed for the front struts, using these electrical connector shells and the appropriate contact pins and 16 gauge wire.
I completed the electrical portion of the suspension conversion back to the OEM Z55 specification, and now this project is complete. Another thanks to @TollKeeper for his help in acquiring some of the required electrical connectors at the salvage yard, and thanks to all of the rest of you folks who followed this project and provided input. Very much appreciated.
My understanding is that these electrical connector shells are also used on other parts of the electrical systems for the GMT900 platform. So, if anyone is interested in having spares of these electrical connector shells, and contact pins, just let me know, and I will send them to you for free.
