After ordering this item I did discover that it might be possible to use a newer design -- and supposedly better -- actuator. (Maybe that explains why the electrical connector fits older model trucks?) Amazon carries this newer model in the form of the "Dorman OE Solutions 4WD Actuator 600-101". Since I did not install this newer design, I cannot say for sure that it will work in older model trucks. However, I did read a number of posts on websites in which the writers claim to have installed the newer model without any problems. I wish I would have known about this newer design before I ordered the 600-100 model.
I also discovered that Amazon sells a 'manual' actuator system. The part for my truck is the "Posi-Lok PSL600 4x4 for GM / Chevy", but Amazon carries this design for other trucks as well. This system is significantly more expensive, but it also offers benefits over the standard electromechanical designs. It also takes much more effort/skills to install.

I found this out after test fitting the part with the wrench. I then crawled under the truck to remove the old part. Surprise! The old actuator has a larger hex head. I used a pair of channel lock pliers to remove the old unit, and the other wrench to install the new unit.
One additional tool was needed to remove the old electrical connector, a flat head screwdriver. I used it to push apart the old connectors instead of tugging on the wires.
In all, the time to gather the correct tools, including the three trips to the tools chest, took twice the amount of time as the actual swap out of the part.
Note, I thought about switching to the alternate mechanical actuator as I think that this type was a moronic idea from GM in the first place. After looking at the cost of the parts, the actuator and the additional wiring from the transfer case to the transaxle actuator, plus the labor to modify the trucks wiring to accept the short wiring harness, I realized that I could replace this type of unit about 5 times.
So I will be patient and wait the extra few seconds. I figure that I'm stopped waiting anyways so that I don't damage the transaxle.
Now, my 4wd works perfect! Plus, it comes with lifetime warranty! Can't go wrong!
