my factory boost gauge has gone bad in my 05 ss/sc an was wondering if i can use a mecanical gauge an if so how do u hook it up. i know how to do it on turboed vehicles just not supercharged any help would be great.

 

whats the difference if you know how to install it on a turbo car? boost is boost. find the vacuum line coming off the intake manifold. put a t in it and run your line to the gauge

 

^^ this. center of the IM near the top has the boost/vac sourse. T in there

 

ok what about for hooking up the light. can i use the existing harness from the factory boost gauge for the light?

 

Make this simple-
