Solving the problem
I spent months reading forums, watching videos, tracking vacuum lines, checking voltage, esentially everything everyone has said is the issue. I got a good deal on the new switch. I would have bought it anyway, but this took me to fixing 98% of my problem. Instead of cutting to defrost around 30, everything works until I hit 70. I have one more line to replace and I think I will be at 100%. Huge milestone though with the winter months coming and needing heat.I want to be clear to everyone out there with older super duties. Not one of my systems worked. It was not just tied to 4x4 or AC. it affected every system. It is also to determine if your issues is in the cab or in the engine compartment. The switch fixed my problem on all systems.

Exact fit and fix
This part was a perfect fit for my 02 F250 Super Duty 7.3 diesel and it fixed the problem I had of the air only blowing in defrost setting.

Worked well with no leaking as others have experienced.
Worked well with no leaking as others have experienced. Cycles properly at higher vacuum for engage and lower for disengaging. Pins are not in the exact position, they are more towards the center than the original, making the connector a tight fit. installed in 2003 Excursion.

Ford Excursion 2005 6.8-V10 - Perfect replacement for FORD OEM part
Ford Excursion 2005 6.8-V10 - Perfect replacement for FORD OEM part. As others mentioned, the two outer pins have to be bend slightly to the outside (use a screw driver, but be careful) and the plug will fit snug. Hub locks engaged immediately again.

Fixed vacuum leak in 2002 Ford F250
Had a vacuum leak in my 2002 F250 and couldn't trace it down. Tested everything piece by piece and noticed the pump ran continuously when plugged into the factory control switch. Ordered this and installed in 2 minutes. Vacuum leak fixed and now I can control my AC vents like normal.
