I purchased this at Yodobashi and opened the package, but I have never used it. This is a parking surveillance direct wiring cord for Comtec drive recorders. Compatible models: HDR-951GW, HDR852G, HDR360G, HDR-751G, HDR-751GP, HDR-75GA, HDR103, HDR203, ZDR026 It can supply power and record even after the vehicle's key switch is turned off. Also, because power is supplied from this product, there is no need to connect a cigarette lighter plug cord or a separate direct wiring cord. Includes a 4m direct wiring cord and 2 electro-taps.
