Carb vacuum routing help needed please

[92470]

Hi, can anyone tell me where I can get a diagram of how my vacuum lines are supposed to be connected from my carb to appropriate ports? I have a 71' Cheyenne with a 350 and a 4 bbl quadrajet. It's all stock, but I am in the process of running all new vacuum lines and want to make sure I get all lines running out of the carb to the appropriate ports. My factory shop manual shows how they are routed for climate control, but to my knowledge not the carb. There looks to be some sort of electronic advance on the driver side of the carb with a sticker on it saying "not to use it to adjust idle", I have no idea what it is and it has 2 ports that have nothing running to them! At some point, someone has substituted maintenance by re-routing things, and I would like to get it cleaned up. The truck runs, but with all of the vacuum leaks and hoses off, I haven't figured out how for this long! Thanks for your help!
