i bought a 88 all-trac with the servo for the awd lying in the back seat. the previous owner had taken it off as one of the vac fittings had broken. i repaired the broken fitting but am at a loss as to the proper hookup of the vac hoses. there should be 4 but i can only find the three coming from the elec/vac switch on the firewall.i have looked at the haynes ans chiltons manual and yhey don't show much on the all-tracs, and my local toyota dealer is less than accomadating when it comes to info on all of my old stuff. if anyone knows or knows of a site where i can view this it would be helpfull. thanks

If you give Toyota your VIN number, you should be able to order a vacuum hose routing diagram to put on the bottom of your hood. These must be available for cars who have front-end damage and have the hood replaced. (I assume you've looked on the underside of your hood for the diagram and it isn't there).

i believe thets the emissions vacuum hose diagram thanks
