YJ vacuum line ???

JOOP · Aug 18, 2013

Over the years and many transformations this vac line got disconnected from somewhere from my 1990 YJ 4.2 blcok. Anyone have a YJ that they could go look and see where it goes? The line is about 3-4 ft long goes into the fire wall, other end unknown...

Could be connected to this? Is the the 4x4 switch indicator for the dash?? If not what is this for? I can't find either of these in my Haynes manual.

Windshield washer nozzles. It's either the one that runs to the back that would have hooked to a wiper on a hard top rear window, or the one that hooks to your nozzles that spray the windshield... I can't remember for sure, but I know that's what it is cause mine is cut right at the firewall and I keep thinking about finding a universal fit type bottle and re-hooking it up, cause windshield washers can come in handy sometimes.

:awesomework:

[EDIT]: And yes, I do believe that's the 4wd indicator switch, I think. Obviously it's not hooked up, pull it out and huck it.

I forget how the t-case indicator works, but on a YJ it would've been tied in with the vac disconnect on the front axle... and of course on your rig, that's long gone.
