Unplug em and see what stops working.

Remember, it's not rocket science; just a car.

Assuming you have dual fans, one is standard fan, other is 2ndary fan for HD cooling application, 3rd is fuel pump relay

See, that's what I thought too.. but I ran the motor, waited for the fans to come on, then unplugged both relays and the fans still ran. Then I read somewhere else that the fan relays were over by the battery so I checked and found two relays there. I unplugged one at a time and the fans went off one at a time.. but the question remains.. yes the big one was the fuel pump because when I unplugged it the car shut off. I have dual fans

That makes sense since I got a check engine light ON when I unplugged them then went away when I plugged them back in... thanks for your answer

I'm really sorry about that answer. I try very hard not to pop off with bs just to have something to say like some seem to. My 91 indeed has 3 relays by my booster as yours are pictured and they do run the 2 fans and the fuel pump. Apologies.
