bought the 12v power harness that connects to the front running lights from smithabusa a while back, to use for my gps to have accessory on power. My gps uses a typical usb cord for the power. What cord are u guys using to splice into the connector to plug into smithabusa's harness? Should i use a normal 120v ac charger that has pos/neg leads, shop the wire and splice it to his connector. Would it work to use the car charger that is supplied with the gps, just chop the cig lighter end off and splice it to the connector for his harness. Basically, kind of confused how people are hooking up their accessory chargers into the harness. Pics would work wonders!!!
