1988 Camry All Trac Electric/Vacuum Switch

Hello. I'm new to the forum hoping to get some help with piecing together an '88 Camry All Trac. I bought the car a couple of years ago with a knock in the engine (3SFE). I bought a parts car with a good engine and after parting out the parts car, I decided to hand the project off to a shade tree mechanic. He swapped the motor and installed a new clutch while it was out but took ill shortly after that and was unable to finish the project.
I got the car back and have been piecing it back together using a couple of manuals and visiting a junk yard. I've got most everything buttoned back up with the exception of an electric/vacuum switch located on the upper left firewall area to the right of the power brake booster. The switch has 3-4 vacuum hoses connected to it that have been cut off and their destination point is not evident. Other Camry models I've looked at do not have this switch so I suspect it's unique to the All Trac models. Can anyone tell me where these hoses go or where I can find this information on line?
Thanks

If the information is hard to find, you may be able to get it from a dealer - or find a factory Maintenance manual for that car.

Thanks. I found a guy with an All Data system and we found out that they are the shift solenoids to engage the All Trac function. The vacuum hoses tie in with a vacuum chamber that does the actual shifting in and out of all wheel drive.
