Speedo Rpm Gauge
 

Hello,
I know I will probaly catch some heat for this post, but Im wanting to replace my boring old white face gauges with some indiglow white face gauges. The kit that I purchased comes with one red wire and black wire. My question is in my 95 stang, do I just wire these into the headlight knob wire or something. I havent taken apart the assembly yet, but just curious. oh, and yes, its somewhat rice, but i like the look of the soft glow compared to just boring stock looking. Any help appreciated...
