Cable connects to a USB port and provides a 3' extension. The female end of the cable features a flush mountable design. You can simply drill a 3/4” hole at the desired mounting location and snap the end of the cable in for an OEM look. The USBDMA3 also features a mounting bracket that can be used to mount the USB connector without drilling holes in the vehicle. Snap the cable into the bracket and mount it wherever your installation demands.
