this will work, you will have to make a jumper or cut the round plug off the one thats there and wire it up. the black cap on it is just a vent/filter(to air), you can pull it off(and it has a metal pipe coming out) and hook up the other(3rd) vac line to it or if needed cap off the vent port(if only needed on application) these work for the AC idle up, fj62 vac solenoids etc, handy to just have around as a spare.....
the bracket can be removed and the bracket for the old one may fit but lots of places it will mount to and look correct.
got this one just a few months ago, think it was around $30
