I bought aeroforce gauge and was trying to figure out where is the best place to tap into for some power. I was thinking the foglight switch and which color wire would that be?

i wouldnt use the fog light switch...that might have constant 12V like the headlights....i dont know for sure

i would use something that you know that has Ignition power....like off the radio or the cigarette lighters (they are on the RAP circut)

hmm, i guess i could run it to the cigarette lighter. that might be safer i guess

Radio has constant 12 vdc supply, power switching is done internal to radio. Cigar lighters are alignable in two different configurations (constant supply, or switched by relay off after 10 minute time delay with ignition off) depending on fuse placement.
