Mark V:35 Channel Switching with Voodoo Lab Control Switcher

I have a Mesa Mark V:35 that I want to do channel switching with a Voodoo Lab Control Switcher. However, I need to either build or buy a custom cable. The 5 Pin DIN plug that comes with the V:35 might not necessarily have the same pinout as the 5 Pin DIN on the Control Switcher. I could also perhaps go 4 mono plugs out of the Control Switcher into a 5 Pin DIN for that'll connect to the V:35. But... I do not know the pinout. Voodoo Lab claims they make a custom cable for it... but like many other businesses, they are using the COVID excuse to not reply to emails and offer terrible service to paying customers. I've been emailing them for weeks.

Can anyone here offer some advice? I can build the cable, I just need to know the correct pinout for each end.
