Engine grounds and vac hoses

[tfalconier]

On my 90 sho by the fire wall the ground going to the firewall isnt connected to anything, and i have some vacume lines off, like the lines for the intake butterflies. Does anybody know where i can get a print out of where all this shit goes, im sure there is more stuff disconnected

A vacuum diagram should be on your radiator cover. Grounds are from the body to the engine or battery. As long as they are clean and tight it is not critical where they are attached.

the radiator cover part is long gone, i know it doesnt matter where the grounds go but i would like them in the right place.

Reprinted from a previous post:

"The routing of the secondary butterfly vacuum lines is from the center tap on the intake's rear plenum to the front (forward) tap of the black plastic accumulator tank. From the rear tap of the accumulator to the bottom tap of the solenoid. From the top tap on the solenoid to the "T" fitting under the idle air control valve. From the side post of the "T" to the rear bank secondary vacuum diaphragm valve and from the front post on the "T" to the front bank diaphragm valve."
