Normally, that the vacuum supply for the booster. That would be a check valve.
I thought ABS systems were pump driven, not vacuum.
An old thread (so please don't bump) but has a pic of the '90s ABS

The vacuum supply is plugged into the right side of the booster, this thing extends from the left side and has a two pin socket.
The brakes work but no ABS.
From all the pictures of XJ brake boosters ive seen I cannot find one with this connection thing.

I Googled a bit and came across a 1998-2007 Volvo brake booster setup. Looks like a match. That connector is for a brake pedal position switch.
