If you know where the boost actuator is then its right beside it, If you are standing at the side of your truck at the drivers side front tire and looking at the engine its the little solenoid the has a two wire plug facing you, it has two vac. hose's on the bottom one is pink and the other is black, at the top it has one black vac. hose now from there if you move your hand toward the blower the boost actuator sets between the dump solenoid and the blower itself. Did that make sense?
