SOURCE: Need vacuum diagram

I can't send you a diagram but I can tell you the basics that should get you mobile. Take a vacuum line from the lower front of your carb and hook it to your distributer vacuum advance. Take another from the front of your carb and run it to your EGR valve. It should be beside the carb on the intake manifold. At the rear of your carburator there is a large line coming out. It should be steel. It provides vacuum boost to your power brakes. Hook it up. Make sure all other vacuum outlets on the carb and intake are blocked off and you should be able to get mobile.

this hose might go to your intake manifold vacuum source, it should go to a vacuum modulator on the transmission. it changes shifting based on the engine load.

The 4x4 will not work. No service light is on. I replaced the switch still nothing but i did find a hose with big holes missin and it leads to the transfer case. Cound that be the reason it doesnt switch?


The hose sounds like the 4WD vacuum switch line hose that connects to the vacuum switch on top of the transfer-case on the driver's side. When the vacuum switch is activated, it actives the 4WD actuator under the battery to lock up the front axle hub in the differential giving you 4WD mode.
Inspect the vacuum hoses and replace and damaged parts and reconnect the vacuum line to the vacuum switch. This should get your 4WD running 100% again.
Thank you for using Fixya and good luck, if the switch is faulty. You can pick one up at Auto Zone, Napa for around $25.00 and can be replaced in about 20 min with common tools.
