I have a 1977 F100. 302, 2V 4 speed M/T. Manual brakes. Non CA truck. I do have a charcoal canister. I have the EGR carb plate, but the EGR hasn't been hooked up since I bought the pickup this spring. I don't have a ported vacuum switch on the drier's side rear manifold nor do I have a ported vacuum switch on the thermostat housing. I don't want to run my EGR, but I do want to operate the snorkel which is hooked up to manifold heat. Can I just tee off the distributor advance to run the air cleaner circuit. Thanks guys! Anyone have a diagram for my specific pickup? I can't find one anywhere.
