Q. about plastic box's behind the batt on 00 L

Black box
 
They store vaccum for your climate control system, mine's no longer there. It just makes your heater/air changes work faster, but are not needed, I removed and plugged mine off due to a Optima battery install. Save them for a stock reinstall, John H.

So i can get rid of all the hoses connecting to those boxs? their looks like a bunch of lines tee'ed together......

Hoses
 
Don't get rid of all the hoses, if you really need to eliminate the box, just connect the in hose and out hose to each other with one of the tees, the system will still work, just a second or two slower, John H.:cool:
