hi, i have an apexi boost gauge but i dont know which vacuum tube to hook it up to. i have a vortech supercharger. any help would be greatly appreciated. also i havent decided where you put the gauge, so if you have any good ideas other then the obvious that would be great as well. thanks

 

Put a vacuum T inline to the Vortech timing control box under dash. Or run the line to any vacuum source on the intake manifold.

 

The blue "T" with the small white tube coming out of it is the one that goes to my boost gauge.

 

thanks guys

 

Good pic for reference, but how about wiring the lighting? Thanks!

 

Look at the red, yellow, red wires in the pic. It's the bottom red one you want for power. Ground can be found if you look up from the fuse panel onto the frame. You'll see a bolt with an "octopus" of black wires going to it. Pick any of these and tap into it for ground.

edit: I was thinking about an a/f for the lights. Sorry.

 

Ok I will try that, but would you know if it was possible for the lights to be controlled by the dim controls on the dash? Is there special connector to do that?

 

On another note, would you know where to wire the air/fuel ratio gauge as well? Thanks again...

 

You need to "T" tap into the primary O2 sensor wire at the ECU. It is the white wire on PIN 16 on the 31 pin connector.

edit: I was thinking a/f for the lights. Sorry.
Illumination of the boost gauge can be tapped into the top spade connector in my picture. Ground the light at the same place you ground the gauge itself.

 

here's where i have my boost gauge hooked up under the hood.
