Hey, I just installed a boost gauge in my a pillar. I couldn't find the light at the time, but I found it. Where did everyone plug in there postive and negitative cable for the light?

 

usually from the cig lighter wires. easist to access.

 

I routed the positive cable from the fuse box on the same circuit as the instrument cluster. There are special fuses you can get to splice in a new wire. Alternatively - and this is a little ghetto, but oh well - just take the naked wire, twist it, and insert it into the terminal where the gauge cluster fuse goes. The negative just needs to go to any ground - I have it on a bolt on the back of the dash.
