My truck is an 84 4x4 pickup that is a California Emissions model. The instructions in the Weber Kit are pretty straight forward. They show the factory vacuum diagram then below that the Weber diagram. There is only one part I can't seem to figure out. One of the emission components is a VCS or vacuum control switch. It has three vacuum nipples coming out of it. Both emission diagrams are very unclear on what vacuum hoses connect to it. Any help would be greatly be appreciated. Has anyone done this legal Weber conversion to a California emission truck?

 

I did the smog legal kit not too long ago... Ill check how I did it tommarow and let you know. The diagrams can be a little confusing at first.

 

i totally appreciate it.
