I’ve worked up a drawing with yours and the other’s suggestion to just use two relays to interface between the VPX and Lancair flap motor circuitry. I’ve attached the drawing. If anyone sees any problems or can suggest how to make it simpler please let me know.
I expect Marc at VPX will be concerned the VPX will use the position senor to stop the flaps and if a limit switch stops it first the VPX will see it as a fault. So for it to work this way the VPX stop settings using the position sensor (not as accurate) will have to be in sync with the limit switches. And the position sensor may not be accurate enough to sync with the limit switches.
A big thanks for everyone’s help!

I think you're making this much more complicated
than it needs to be. See:
http://tinyurl.com/lel2jep
You don't want to ground the flap motor power
on the instrument panel ground bus . . . that
goes to the firewall ground.
As you've noted, pins 5 & 6 need to be identified
for which one is +extend and +retract.
You want to disable the VP-X limit switch functions
or nullify them by programming them outside the
points where the limit switches operate.

Thanks Bob – that’s much simpler and elegant. As I looked at your design I just kept saying “Bob’s a genius…” J  I think I was stuck on preserving the Lancair circuitry instead of just solving the problem.Â
Thank you very much!
