I'm puzzled how to get sufficient power to my Icom dual band mobil radio. On one hand it looked easy since battery access seems readily available in the 2014 C-Max Hybrid - it's right under the real little cover....but what terminal is 12v + and which is negative? There is a wire going to the chassis which must be ground but I'm really hesitant to do this with out some guidance as I could tap into the wrong terminals! It seems like Ford doesn't want us to know. I'd really like to not go through the firewall which appears to be VERY difficult and of course at full power the radio will draw too much to use an accessory outlet. Any suggestions would be appreciated.....along with a picture since it's much easier to explain your solution that way. 73 Rick, W2JAZ
