Post Quadra-Trac

Could someone explain how this transfer case works? What does the emergency switch do and how does it work. It looks like there is a canister on my firewall that I think is to work in conjunction with this transfer case but it is not hooked up.

here is the scoop on the quadratrac since I own 3 of them.77CJ7 2 78 CJ7's

Start from the inside. IN your glove box there is a small switch. To the left it is normal four wheel drive. And to the right is emergency 4wheel drive. Coming from the engine a vaccumm hose should go to that switch cause it is all vaccuum controlled.Three hoses go into the switch. Two go out through the firewall and down to a set of steel tubes that go to the shifter relay valve on the x-case. There are two steel tubes on the end that is where your hoses go. MAke sure they are clamped tight or they will leak. There is a small steel tip on the top of the case that an electrical wire goes onto. This turns on the light on your speedo when emergency 4wheel is engaged. This orange wire runs from the case to below the fuse block and hooks into a two prong clip. One for the orange wire and one for the yellow tranny kick down wire. Since you are running quadratrac you have an automatic tranny the chevy TH400. The small canister on the firewall has nothing to do with the quadratrac if it islocated on the drivers side it is a charcoal canister for the emissions If you would like to email me please feel free to do so @ gone_jeeping_2001@yahoo.com and i could give you my Phone # and talk you through it if these points dont help much
