I am getting close to doing the vacuum lines on my 86 Shelby Charger. I want to keep the setup as simple as possible. My questions are: Does anybody have a vacuum diagram I can use showing only what is essentially needed? What is a simple PCV setup? What is a simple evaporative emissions setup? Can I eliminate EGR without setting any light/codes and for that matter will eliminating any of these systems set any lights/codes?

I have an 85 glht and use a fwd LM. I have 1 line to the map, 1 to bov, 1 to wastegate, 1 to fpr. No evap and no egr I get no codes.
yeah you only need 1 to map, one to fpr, one to bov and one for boost control for all the small line stuff.
then you should have some breather/PCV setup. lines that are larger.
i prefer (2) 5/8" breather tubes to the valve cover (cast TBI cover is perfect for this) and then the PCV line from the intake manifold to the valve cover to do a little draw when the engine is in vacuum.

You don't need to use the solenoids on the fender. I do like to use the baro read solenoid as it's a good idea especially if you live in an area with elevation changes.

here are factory diagrams. these show the solenoid before the map (baro read solenoid)
typically the other two solenoids on the fender area are the purge solenoid (for the charcoal canister and vent line from the fuel tank) and the boost control solenoid.

What kind of condition are the charcoal caninster and associated bundle of hoses in, visually? Would you be interested in selling them?
They are in pretty good shape, but I want to keep them around as I think someday down the road I will want to do a factory restore on this car. I'm getting back into the car lately so I may be doing the vacuum lines here within the next week and may report back here with more questions.
Looking at the diagram there are all kinds of check valves and orifices. Do I need any of that? I can just run straight lines to the map, waste gate, fpr, and bov. Does a stock 86 T1 have a bov?
The log TI cars don't need a BOV since they are not a blow through car.
I don't use any check valves or orifices, I just run individual lines to most things.
the only one that i might use orifices with is the boost control so that the ecu controlled boost tables dont need re-calibration.
if you are using a manual boost controller or feel like tinkering, then delete them.

Ok, after looking at the diagram again and reading through this thread I have a good idea of how to run everything. Next question, which solenoid is which out of the 4 on the passenger side fender? I plan on using the boost control and Map/baro. EGR and EVAP will be removed, and PCV setup will be simple.
i usually take a look at a wiring diagram for the wire colors to figure out which solenoid is which.
