1983 k5 silerado , 350 engine , 700r4 trans , cruise control gutted. when i open the hood , i see two vacuum controlled cylinders on the firewall , one to the left of the carb and one to the right. the one to the left has one vacuum hose in and 2 wires going somewhere and is still connected to vacuum ( for the trans maybe ?? ) the one one the right had one hose in , and what looked like a hose fitting going out. it too had wires connected to it i ditched the one one the right with no ill effects , manual doesnt show wiring for these controllers If the one on the left isnt important i would like to ditch it too. left over cruise control crap ?
