Like SS3011 said, get rid of the booster and install the 9C1 police car brake master cylinder with the 1-1/4" bore size.

RockAuto has brand new master cylinders with the reservoir, Wagner P/N MC131285 on sale for $34.00.

Also, search for a 1993 to 1996, 9C1 police car brake pedal assembly with the pushrod. They have a different brake pedal pushrod lever point.

Does that work well with Disk Brakes?

here is another pressure switch

This is similar/same as what they use in the COMP and similar vacuum pumps If you want switched pump operation .

How would this attach?
Directly from the pump to the Booster?

Dan ,
switch goes in booster vacuum hose between pump/booster.
The kit you bought is just an easier package .
Good luck

Yes it does work with both the OEM and aftermarket 4-wheel disc brakes.

The same pump is also used in Volvo's, Subaru's and other car models. The mount bracket for the Auxiliary Pump is GM P/N 25920516.
You can get the connector either at the dealership or NAPA.

This is an install video.
