Need help with CEL codes 850 1997

I have a 97 850 glt.
My CEL is staying on after resetting and the codes I was able to pull are P0243, waste gate solenoid malfunction and P0410, secondary air injection system.
I know the second one is air pump related and I have to diagnose for pump vs. relay etc... The first one I'm not sure about and don't know where the waste gate solenoid even is. Any help or suggestions would be greatly appreciated.

    Although when I hear the term "wastegate", I think turbo, although since you have the air pump, I guess you're not a turbo. If the wastegate being referred to is somehow related to the EGR, I'd bet fixing your pump would fix this code.

    The only time I have heard of a non-turbo engine shooting out turbo engine codes was an instance where the owner took it to a gen-eu-ine Volvo dealership where they pulled completely seperate codes from the computers.

      The 97 glt has both a turbo, low pressure that boosts to 7 psi as stock so yes it has a wastegate and an air pump too.
