transfer case vacuum modulator

Where exactly on a 1988 GMC S-15 Jimmy is the transfer case vacuum modulator? And what exactly does it look like? Getting ready to install my body lift and I have to add extensions to the hoses on it. Want to have everything preplanned before I begin!
Thanks alot!

<font face="Comic Sans MS"> 2 possible places. Either on the passenger side inner fender, or under the battery on the passenger side. If you still can't find it, look at the passenger side of the front differential, and you'll see a cable coming out of it. Follow that up and you'll find the modulator...

If you have the 2.8L V6, its on the passengers innner fender. If you have the 4.3, its under the battery. You shouldn't need to lengthen the hose, though.
Good Luck.

Re: transfer case vacuum modulator

When I put in my body lift mine was located on the passenger fender. I just drilled two holes into the fenderwell and moved it down on top of that.

just an idea.
