Relays

Does anybody know which relays control what,I went to a dealer
and the service mgr said he didn't know(DUH).
My vehicle is:
89' Cherokee Pioneer
4.0 I6
Auto
4x4
air
cruise (no worky)
This thing is all stock,cept for the grille(painted flt blk)

Working front to back in the covered cluster: O2 Sensor Heater Relay, Fuel Pump Relay, Power Latch Relay, A/C Clutch Relay.

One of the relays on the passenger inner fender is for the Aux Fan

The Electrical manual for that year is more descriptive and addresses many of the others, but those qty=5 seem to be the most asked about...
