I have a class with a 307 in it but the engine is no good. I have a replacement 307 but it has a smog pump on it.all the wires connect except the little vacuum line box thing on the driver side of the carb hooks up. How do I hook that up or change it.

 

Pics would help.

 

I will not have pics until the weekend but its the egr control solenoid I'm talking about. They are made different.
