I know I have to T off a boost line to connect it to the nipple on the controller. Can I use the bypass valve line? Also whats the size of Vacuum hose so I can extend it to the controller. Thanks in advance

Tee it into the boost gauge line or the line that goes to your map sensor. The polished stainless steel port on the controller is 1/4 - 3/16. You can use 1/4, 1/8 or 3/16 hose to connect to it as it has a reducing barb. Even the nylon hose that comes with the kit will fit NICELY over the barb. Most likely your hose in your car is 1/4. If so you can connect directly to the controller.

Eitherway, its a piece of cake. Thanks for your purchase.
