Litnin, I see the nipple on the firewall between the two A/C hoses and I see the hose on the throttle body but it goes directly to the cruise control(no tee). The nipple looks almost too small to fit any of the vacuum lines tightly. Is it possible that nipple was not used for my model year ('88)? I honestly cannot remember ever seeing a vacuum hose on that nipple. Still trying to get this squared away. Thanks for your input.
