Secondary Air Pump Fuse

Secondary Air Pump Fuse
Okay so I have had a cel on for months now and took out the pump and determined that it was the problem. So I ordered a new pump and just installed it the only issue is I cant figure out where or what the fuse for it is. I'm almost positive its the empty slot in the picture below but Im not sure, the picture was taken just to the left of the ECU. If I am correct and that is the slot of the secondary air pump fuse than what kind of fuse is it?

Looking for a blown fuse. Take the key out of the ignition, and check all the fuses on the driver side fuse panel first, by pulling each one out individually. I think secondary air fuse is there.

on a B5 there is a relay IN the ECU box. test it as shown in my thread above, if it is good, you have a good new SAI pump, so no problem there. remove the plastic output line from the pump, and start the car. you should hear the pump screaming. check this plastic line for leaks - I duct taped mine completely to stop a few leaks there. then check rubber elbow on metal line to combi valve. you must remove the combi valve and test it. I've got posts on all this under my name. good luck
