What are the bare minimum vacum components required to have connected for a 4.0 to run normal? Map, egr, brake booster? Anything else?

I'm trying to eliminate all this unecessarry shit. :confused:

count me as interested in this one to, I believe transfer case, gets a line as does the front axle, for the disco, if you've one posi lock that one is obviosly redundant

big mess in there eh?

Yeah, I don't care about the t-case, or front axle. I just need the engine running properly and then I'll take it from there.

Did you read my question?? :shaking: I'm looking for the bare min, not what the factory calls for. Seeing as how the engine is in a completely different rig, the diagram doesn't even apply.

Junior33 - All that you need to run is the MAP, Fuel Pressure Reg, and the brake booster if you like power brakes.
