ok so I'm trying to hook up power to my arm air fuel gauge my boost gauge oil pressure and my his evc… i know a lot so i decided i want to use a relay from a constant 12v source. i found the white wire underneath the steering column that is constant. it is a thicker wire so i assume its much safer than just plugging into the acc behind the head unit. idk think its 14 g maybe. anyway i never wire in a relay before so this is the diagram I'm going to follow up on..
the connect for the turn on lead does that need the acc source I'm not sure what that means really
