Secondary Air Pump Relay Location
From what I have gathered reading other post is that my secondary air pump relay is in the fuse box under the hood. I've found two 40amp fuses in the box (one is for secondary air) so, I'm getting close but, I can't determine which is the correct relay for the pump.


Someone please tell me which relay is for the secondary air pump.
