Help How to wire in vacuum guage Can anyone point me in the right direction where to connect the vacuum gauge wire. I have heard just to run it to one of the sensors but which one and how, Im used to old school Camaro and need guidance. Thanks in advance
If it has a vacuum line you will have to "T" into a vacuum source coming off the intake rather it be the MAP sensor or the line going the HVAC. If you use the line going to the HVAC make sure you "T" into it before the one way check valve so you are getting a true reading from the intake.
The electrical versions I've seen use its own MAP sensor. I don't know if you could use the MAP sensor already on the car or not. I "think" the only way it would work is if the gauge uses the same voltage table to determine vacuum/boost. I do not know if there's a standard for those values or not.
