Next time try asking the question, in normal form...

The air pump actuates the 5th & 6th ports on a S5 Engine (N/A)...

what was the reason for removing it in the first place? Did you remove the cats also?

An 87 is an S4, the aux ports are actuated by back pressure from the exhaust not the air pump. Unless someone has converted yours.
