Code reads po491 secondary air injection system bank 1. I was told it's either the relay or the actual pump. I bought the relay but I cannot figure out where it's suppose to to. Can somebody help me and tell me where it goes

 

back of the engine near the 02 sensor harness connector

 

I cannot find that dam thing anywhere could ypu maybe take a pic and show me that way. I'd really really appreciate you

 

i dont have an avenger. all i can say is: find the pump and follow the harness back to the relay
