Please help....I have no clue what to do

[jpwf2020]

So I've got a 1998 ranger 4x4 with a motor out of a 1995 explorer. I bought the truck with an engine on a pallate and no engine in the truck. I have it all back together with the exception of a vacumm line running from the throttle body.... I don't know where it goes! I have a 1997 explorer with the same motor and the the line runs to a mechanism under the battery with another hose running out of it and a knob on top. On my truck the mechanism has a line running to the front differential somewhere and one running towards the back of the truck. Idk where to plugg this vacumm line into. Any help would be much appreciated.

need pictures.

the mechanism with the "knob" on top sounds like the EGR control solenoid.. but thats just a guess. you could also be describing the EVAP purge solenoid or the evap canister

given the information "running from the throttle body" my best guess would be its the EVAP purge solenoid.

just get a picture

a 98 ranger has vacuum hubs doesnt it is all your 4x4 stuff working?

sounds right to me. i only know of one line off the throttle body and that goes to the solenoid.

as for it being for hubs, they would not be getting the vacuum from the throttle body, they would be getting it from the upper intake.

That 98 should have a vac cannister with vac lines coming from the engine and going to the transfer case and also the front axle. The cannistor keeps a supply of vac in it so when climbing a long hill and the vac drops off the front axle stays locked in.
It' easy on the old wranglers. They have different bright colored plastic vac hoses.
