what to do with Vacuum pump for NV4500 swap

[Finnegan1008]

I have collected almost everything I need to do a NV4500 swap on my M1008.

when doing this swap what is the protocol for the vacuum pump? I believe it's only use in a CUCV is for shifting the TH400, is the correct?

Also mine is leaking (badly) should I cap it off? Can I delete it?

The lower part of the assembly drives the oil pump. You can either pull the guts of the vacuum system out and seal it up or install one of these. Which is what I did when I swapped to a 700R4 which doesn't need vacuum.

Or if you want to run a tach they also sell an oil pump drive with speed sensor. But it is $$$$

I know these have a vehicle speed sensor built
In… can you wire a tach to this?
