Well i got a new boost gauge today and im going to install it tomorrow. The gauge has 3 wires; Ground, 12v constant and 12v ignition. Im planning to connect the 12v ignition wire to the 75x post under the dash, but i have no clue whats a good source for the constant 12v... Anyone know where i should hook up the 12v constant wire to? Thanks.

 

Check out Audidiy.com they have tons of write ups. I thought I read you hook them up to the lights in a DIY but I can't remember.

 

Thanks, but i read those and unfortunately didn't find what i was looking for. I heard you can hook up the 12v constant to the 30 terminal, next to the 75x anyone know if this is true?

 

Ive found some info on this, according to this tutorial, you can connect the 12v constant wire to the radio fuse and the 12v switched woud be connected to the ESP fuse. Anyone know if this is a good idea?
