Before you begin
This guide will show you how to replace the 12 Volt accessory power outlet in the trunk of a 2010 Volvo C70. We used a Waterproof Male 12V Accessory Outlet in this guide, but any male type 12V accessory power outlet or cigarette lighter socket should work. This part allows you to power devices near the rear of the vehicle through plugging it into its outlet. This outlet would not power any devices plugged into it. The fuse for the trunk was intact and the socket showed signs of water damage in the form of rusting of the interior receptacle. Since this deals with an electronic component, it is important to remove all sources of power via turning the car off and disconnecting the battery before working on it.
