I am having a problem getting the door for inside/outside air to work right. Does anyone know which hoses go to what. They are labeled 1,2,&3 on the controls One is incoming Vac, One goes to door in the cab and one goes to the door in the cowl. There also is a valve on the heater hose that has to tee in to one of those lines. Any help or reference where I can look this up will be appreciated. Thanks John
