Mine looks like this right now but I would also like to know how I should set up my charcoal canister... anyone got any clue where each hose goes? Ive labeled the can ports 1-4.. Yellow are my current vacuum lines.

The way the hoses are identified should give you a pretty good idea where they should be connected. But be advised that due to the fact that you have eliminated the "EGR/PURGE TVS", the EE system will not function as well as designed. If port 2 is properly connected to the fuel tank, when the engine is off the canister will adsorb any hydrocarbon vapor that flows into it. Same goes for port 3 - if it is connected to the carburetor bowl vent. But without the vacuum signal - from the TVS - which is required to pull the purge valve open, some of those vapors never get drawn into the combustion air stream. They (the vapors) will just stay there. Eventually canister's carbon bed will become saturated and won't adsorb any more vapor - after that any more incoming vapor will just spill out to the atmosphere.
Here is a good drawing (view is from forward looking back) and explanation of how GM's purge type canister works:

This system Fig. 63, absorbs and stores fuel vapor in a carbon element until it can be removed and burned during normal combustion process. The canister is equipped with a vapor bowl vent control valve and a
canister purge control valve which are both mounted on the canister.
The bowl vent control valve operates as follows:
- When the engine is off, there is no vacuum through the vacuum signal tube to the valve diaphragm, spring tension opens the valve. Fuel vapors formed in the carburetor float bowl are pressurized to the point where they flow from a tube in the carburetor float bowl through a connecting hose marked ``Carb Bowl'' in the canister cover. Vapors travel past the open vent valve through the filter in the canister onto the activated charcoal, where they are stored until purging of the canister occurs. When the engine is running, vacuum is supplied through a tube marked ``Man Vac'' to the vent valve diaphragm. The diaphragm moves upward, raising the vent valve upward, against spring tension, allowing the valve to seal the passage venting fuel vapors from carburetor float bowl to canister. When engine is stopped, spring tension opens the valve to allow venting of the carburetor float bowl.
The
canister purge control valve operates as follows:
- Fuel vapor is inducted into the engine and is controlled by an orifice in the purge control valve. Ported vacuum signals to the purge control valve is controlled by a thermal vacuum switch (TVS) which delays purging until a specified engine temperature is reached. With throttle closed, the purge control valve diaphragm is seated by spring tension and no purging occurs. With throttle opened, ported vacuum is applied to the purge control valve. With vacuum applied to the diaphragm, the valve is opened when ported vacuum develops sufficient force to overcome preload of the diaphragm closing spring and purging takes place until the throttle is closed to a position which reduces ported vacuum to a level at which it can no longer overcome diaphragm spring tension.
I've edited your post above so you see what it would look like.
