So, this write up is for those who asked to see how I did it, tapping into the speaker grate for power. Pic #1: Opened grate, showing unused plug. It was tapped down with a piece of blue transparent cellophane tape. You can see the small frayed area on the label where it was taped. Pic 2: Case fan extension cord with the female end cut. Note it's 3-pinned When plugged into the connector, the BLACK wire will need to be lined up with the BLACK wire on the connector. Pic 3: Cut DR650GW-2ch power cord Do not connect the ends until the power cord is inserted into the cavity behind the grate. Then. splice the ends together, black to black, yellow to red. Middle wire of extension cord is not used, but I kept it for tensile strength. Pic 4: Use pry tool to slightly enlarge the gap between the windshield and headliner. A piece of coat hanger wire is inserted to probe and establish the passage for the power cord to be inserted into the space behind the speaker grill Pic 5: Power chord successfully inserted. Now join its ends to the extension cord's Plugs are connected and secured by a small zip tie. Pic 6: DR650GW front camera attached to windshield Pic7: Use pry tool to tug co-axil cord along seam between headliner and windshield. Cable should "slip" behind headliner easily. Pic 8: Loosen the bolt (I believe it was a 7 mm) to loosen the A-pillar to insertion the cord into the seem between roof & A-pillar. Pic 9: Once the cord is hidden in the "vertical" seam, it can then be directed to head to the back of the car, and is tucked in the weather stripping. Once the coaxil cord reaches the horizontal seam at the top of the B-pillar, repeat the process of tucking it into the seam and proceed towards the back. Pry tools are extremely helpful.
