Anywhere you want to, just extend the vac lines. Mine is under the renix coolant bottle.

You can get the softball sized one from a newer XJ. They're smaller and easier to relocate.

That football sized canister on the Canadian XJ's are actually larger than the on the US models because the CFL ball is bigger than the NFL ball.

If you have cruise control you'll probably need the bigger one. The Renix with CC had a two chambered reservoir, one side for cruise, the other for heater and axle. If you don't have cruise, the softball should be fine. If you have a later model without cruise, the only thing it affects is the heater controls. If yours is an early model with axle disconnect, you will need at least some reservoir in action or you'll lose 4WD under low vacuum conditions (like just as you get to the critical crest of that snowy hill!). If you have cruise and don't like the options for mounting a big reservoir, you could mount two softballs separately, one for cruise and one for heater and axle.

He has a 1989, so he should likely stick with the "capsule" rather than the smaller "ball" as he may have the D30 CAD in his XJ.
I mounted my "capsule" upside down under the pressure bottle in my 90--drilled two holes and reused the bolts that had held it to the bumper.

I moved the one on my '98 XJ over to the other side in between my master cylinder, and air box when I put my new front OR-FAB bumper on. I do have the smaller baseball size one though.

I put a softball in my 92 MJ, and the cruise control works great.

Could be maybe sort of?
IF you have the NP231 transfer case--2WD/4HI/N/4LO (no full-time option) then your XJ would have come stock with the D30 CAD vacuum disconnect axle.
Symptoms of low vacuum: intermittent 4x4 operation (D30 CAD axle); intermittent cruise or no cruise; heat shifts to defroster vents when the engine is under load.
