With a complete 1994 Aero as a donor car this should be tedious but hopefully fairly straightforward. When removing brake lines and brake pump/booster elements, take your time. Use lots of PB Blaster, tapping, PB, tapping, PB to loosen the connections...I BROKE 2 OF MINE like a ham-fisted moron.
One thing you might find is that your 1992 TCS pump has 4 brake line outlets (2 front, 2 rear) wheres non-TCS 94 pump has only 3 (2 front, 1 rear). In which case, you'd need to couple the rear brake lines into 1 and connect. This may not be the case for you, but it was for me with my 1995.
Killer combo; the best of both 9000's. Good luck!
