Incomplete boost controller kit (Blitz dual SBC)

A previous neighbor gave me this Blitz dual solenoid boost controller. But it's only the controller without the rest of the parts. Is there anything to do with it alone? Is there any point in trying to find the missing parts somewhere to get a working kit or am I better off finding a new and complete boost controller? I'm thinking the missing parts would cost as much but I thought I'd ask before I get rid of it.
