CTO hose routing

I'm the 432nd owner of an 83 CJ-7 with 258, w/ carter BBD, without the comp. on the back of the carb.

I'm trying to figure out the routing of the hose from my CTO swicth...

Right now, I've got EVERY port on my CTO plugged. I believe that most of the vaccuum and EGR controls have been disposed of by the last owner.

Looking in the engine bay, I can't find most of the required pieces.(TVS, chk vlvs., acel/decel sol., etc.)

All I've got is my canister(w/ the 4 hoses), CTO switch, and EGR(which may not be working)



Here is an attempted diagram....

____________Intake Manifold_______________

Let's call the CTO ports: 1
2 3
4 5

What is the bare minimum of vaccuum hoses required to run properly and efficiantly?

Thanks for reading,

Tim
