Gx470 P0418

I installed a Rutech bypass and block off plates and my initial check engine light went out.  A day later I get the P0418 error telling me relay A is bad or there is faulty wiring etc.  

Does anyone know where the SAIS relay is located for P0418?  I have been searching to the point of insanity. :)

 

thank you

For a P0418 that’s gonna be relay one, I suggest getting a pump proxy pack from Hewitt-Tech to close the circuit on your broken pump. You should initially check the fuse for it first to save you the hassle of having the buy the PPP.
