In addition to the original ground, I had also been grounding the vehicle. After selling the car it was installed in, I kept it at home, but I will be grounding in a different way, so I am putting it up for sale. It is not unused, as it was a cable used in the engine room, so it has a corresponding amount of wear and tear. I have confirmed that it conducts electricity before listing it. Two Insulocks and M6 screws are missing, so please purchase them at a home center or similar at your own expense. IGNITION EARTH to enhance the grounding effect. - Brand: PIVOT - Product Name: IGNITION EARTH - Cable Length: Approximately 60cm - Instruction Manual: Included - Terminal Shape: Ring Terminal Thank you for viewing.
