Hi I've just recieved a boost gauge for my 95 wrx and i'm a little confused with the wiring. The gauge has 3 wires - Black, White and Red. Instuctions suppiled say black and white must be connected to battery (+-) and red to car ignition. Does this sound right? Also where is the best place to connect the ignition wire? Thanks.

 

Sounds about right, I wired mine into the radio, will search for a link, hang on
