CJ - Quadratrack Vacuum Ports

I'm trying to run the vacuum lines for my emergency drive shifter, which locks the tcase differential. On the vacuum shift motor for a 78 quadratrack there are two ports, one toward the front of the jeep and one toward the back. Which port engages the emergency drive lock and which port disengages the locked diff. thanks.

The front one locks the differential, the rear one unlocks it.

Easiest way I do it is with both lines unhooked, observe which position the switch is in, start the engine and feel the two lines underneath for vacuum and hook the one with vacuum up accordingly. Then hook up the other one.

Beats trying to follow the vacuum lines.

Re: CJ - Quadratrack Vacuum Ports

No problem. One thing I did a few months ago was move the vacuum switch from the glovebox to the dash. I mounted it between the door and headlight switch. Here's the best shot I have of it right now. (thanks to riogrande's web site from the bash.)

Re: CJ - Quadratrack Vacuum Ports

yeah right now my switch is dangling on the floor boards. i plan to mount overtop of the speaker grill, cause i can't mount it in the glovebox because the cage is in the way of the door.

this is on a project of mine i've been building for the past 2 1/2 years. got it from a guy who was in the middle of a restoration and gave up after he tore everything apart. finally got it moving under its own power about a month ago. since then its been nothing but electrical problems, not to mention it wouldn't shift out of first gear. but all thats fixed now and after a coule minor things like brake lights and this switch it'll finally be road worthy.

whats with the flag in the picture? did you run over a bicycle?
