"California" Bocar 34Pict3 vacuum connections

I have this new bocar 34pict3 california version carb. It is the one with
the throttle positioner. It has some vacuum hose fittings different than the
normal 34Pict3. One is at the very back middle. One is at the back near the
bottom. This one is already connected to the throttle positioner. There is
one on the left side at the bottom of the bowl. There is one on the right
near the top of the bowl. On normal 34Pict3s there is a fitting on the left
in the middle. The cali version doesn't have this fitting. Looks like it has
a place that you could drill out and put one there but it doesn't come with
one.

Anyway, I have a electronic ignition distributor (no vacuum canister). So my
question is what the heck do I do with the 3 vacuum connections on the carb?
And since there are 3, what do they normally hook to?
