This is a Volvo accessory to add a 12V outlet to the trunk or cargo area of your 850, S70, V70 (series 1), 960, S90 or V90. It might fit the S80, but I am not certain. I bought it for my 945 but it has a harness that's not compatible, so I'm going another route. It's sold as a companion accessory to the cooler box, but of course you can use it for whatever 12V appliance floats your boat.<P>Includes mounting instructions, in Volvo packaging (really just a polybag).<P>Price $50 delivered by priority mail in the US. Check or PayPal OK.
