Big Black Pill Looking thingy

Nick_XJ90 · Mar 19, 2008

Hey i have had my XJ for about 2 years now and that whole time i have been trying to figure out what that:shiver: :dunno:

Big Black Pill looking thingy on the front passenger side behind the bumper is. it is a 1990 with a AW4 and 4.0L non-disconnect front axle (found that out after i bought the posi-lok thing).

vacuum canister

It holds vacuum in volume kinda like a capacitor.. Without it your cruise, a/c and other stuff wouldn't work properly.

It's a time capsule....from 1990.

These guys are spot on. It is indeed a vacuum canister.

Can I have my cookie now, or perhaps a button?

That's the "black box", otherwise known as the "wheeling recorder". It will be salvaged by the NTSB for data regarding the downfall of your XJ upon it's demise.

Nick_XJ90 · Mar 19, 2008

can i move it somewhere so its not so in the way of me building a stubby front bumper cause i see some other XJs without it. and my cruise never worked since i bought it and A/c I live in Canada a few weeks ago it was minus 35 and now its only plus 4 and i am going to make a compressor out of the A/C anyways.

I think you are talking about the air bag sensor under the drivers seat. Vac canister on 97+ is still behind the bumper, I moved mine to engine compartment.

I don't know, can you?

Its been done before by quite a few people, it isn't that hard. If you are building your own bumper then moving it should be pretty easy for you.

It's a tracking device installed by the government.

They're watching you, always watching you...........

Nick_XJ90 · Mar 19, 2008

thanks everyone now that i know what in the hell it is i will move it somewhere hmm engine compartment yea that will work.

The airbag sensor is under the console if I remember correctly.

on my 97 it is under the drivers seat, I water logged it. now my air bag light is on. it still hasn't had the recall done on it. When the recall is done they move it under the console. I am just not that worried about my air bags to have the recall done. I think 99+ they started to put them under the console from the factory.

I removed mine when I changed my bumper. I just plugged the vacume line and everything went back to normal (cruise, ac, etc.) except for my air temp thing in the overhead console. Is this bad, should i put it back on?

If you follow the hose it goes to a T connector behind the battery. I moved the connectors around, trimmed the hose, and put the canister in the big opening next to the blower motor. Works fine.
