77 TA vacuum Pipes

[carterdj]

Hi all,

I am in another pickle

I have no idea of the correct placment of the vacuum pipes on my 1977 pontiac 400. The pictuewr in the service manual does not make a lot of sense to me as i don;t have all the bits on there. I have sent Robin and email at Autopontiac, but i am trying to cover all my bases. Here are some pics. I have tried to number the pipes for reference. It also has a charcol canister but no EGR valve or the one connected to the air cleaner (EFE value?)

I also have a thick brown wire coming from the loom (uncer the txt for pipe 7 on right hand side) I have no idea where it goes but it is live when ignition is on!


Any help before the petrol and matches come out..............

Thanks

Darren

i would just try and run it see how it runs and block off all the leaks as long as the dizzy has a pipe and the servo

Yep,thats how mine is/was plus the one from trans,looks neater without all the un needed crap as well.Not sure what that brown wire is but looking at thickness of it i can only think of two underhood wires that size,alternator and starter solenoid,what type of connector does it have on it?,at first i thought power for dizzy but its wrong side and too thick i think.

has it got an electronic choke? has it got a wire connected to it? if not, should the brown wire go there?
