3.3 TB modification

[Nemesismachine]

I picked up the 3.3L throttle body, can I just thread a nipple into the top for the 2 canister purge ports? The 3.3 only has 1. Not sure if anyone else has used this TB before and can shed some light on it.

I've used that throttle body but mine had both ports. One port on the two port one is "manifold vacuum" which is vacuum all the time and the other is "ported vacuum" which is vacuum only with throttle open. Look at a two port one and see which is which and don't drill the holes any bigger than on the two port one.
