Anyone have a vaccume hose diagram for a stock 305 tbi? I found some wierd hoses with a bunch of "T" splits around the back of the engine bay up to the Cruse control valve thing and they are all tore up. some of them have plugs on the end that dont go anywhere.

#1-Thanks tunedperf. the diagram for the 305 tbi auto shows one line running from the back of the TB to the MAP sensor.. Mine does that but has a silonoid on the line that "Y's" off and runs down behind the driverside headlight to the Cruse Control it does not show that on the diagran is that suppose to do that? before it gets to the Cruse Control it "Y's" off again and has a plug in one Air hose and the other directly plugs into the cruse control box. I dont even have cruze control on my steering wheel so its kinda wierd.

#2- I have some wierd plastic silonoid looking with 2 thick hoses attached to it that sits on my pass. side valve cover and kinda flops around...that too has a small air hose attached to it and im not sure where that goes either.

 

the map sensor should never have a y off of its signal. the cruise you might ask some one on the other post to post it I think there should be a vacuum bulb reservoir but I don't have a picture of how its plumbed.
