Vehicle Security Module (VSM) Pinout?

Been lurking for a while...been a Ford fan since my 85 Bronco in early 90's. Reading the post and pretty much never had a question that never was answered at least a few times before...until now.

So now I have 2006 E350 with the 6.0. I was working on rewiring the doors with power mirrors and pre-running for heated glass & maybe a few other things. And while I had my head down in the passenger foot well, I saw this.

If I recall correctly from my previous reading, this is a VSM, not the more frequently refered to GEM module(redunant?) of the same vintage in the Super Duty pickups. (I think Ford really took advantage of the pure utility mindset of E-series buyers and skip updates wherever they could.) And where the big white line is, is a 5-digit number that resemble what second hand owners of early 2000's Super Duty owners with door keypads and no passcodes go hunting behind the middle of their dashboard for.

So here's the can of worms i want to open. I want a keypad. I did not see any extra pins on the main harness for the doors. I don't see it at all as an option on my van parts diagram. My 2006 Wiring Diagram shows the connectors C203a and C203b as the connectors for the VSM, but the pinout shows a lot of unused pins.

I'm going to assume that the module is universal and not hobbled by Ford in any way. Does anyone have an older Wiring manual that has complete pinout reference so i can run wire for a keypad. Maybe the trucks guys have a more comprehensive list? Maybe the OEM? Anyone know who OEM was?

Thanks in advance.
