i recently installed after market head unit stereo (sony) into my chevy colorado 07 , the harness doesnt connect ignition wire (red) to the factory , so i tapped from a wire to ac control underneat the stereo .
It is working as i wanted except when i crank up my AC above 2 (my ac run from 0-4) the radio shut down
Im thinking of running wire to fuse box under the hood but im not sure how or where to connect the wire to, do i need special tool or just stick a wire in?
Thanks!
