'98 Rodeo A/C Compressor Won't Engage

Just finished replacing the timing belt, water pump, tensioners, cam and crank seals on my Rodeo. A/C was blowing ice cold. As soon as I took it around the block for the test ride, I realized that the compressor wasn't engaging. Checked the fuse - good. Relay clicked when blue A/C switch was pressed. Not sure what else could it be? Hopefully I didn't do something when I changed all these out. Everything else is working great.

No thoughts anyone? Hehehe, I guess my plan of action will be to borrow my Dad's A/C manifold set, check the pressure on the High/Low side, and check all the electrical connects. Is there any way to bypass this to see if the compressor is still good? i.e. if the clutch will engage, etc.
