A New Boss Headlight Adapter MSC09993. In this kit you get the HB5 plow side plug, to the H13 truck side harness MSC08839 and the turn signal relay kit MSC09991.
This kit does work on other brands (Fisher, Western, Blizzard, SnowEx and Meyer) if you already have HB5 light adapters and you are installing it on a truck that has the H13 headlights.
This is used on these and possibly more. 2009-2014 Ford F150 2005-2016 Ford Super Duty (Made sure your truck lights are H13) 2016-2019 Ford F650 & F750 2006-2014 Ram Trucks 2008-2014 Ram 4500-5500 2007-2017 Jeep Wrangler
This is for the Boss 13 pin harness, they come with an HB5 plug built into them and this adapter converts that HB5 over to an H13 plug. This will not work with the old Boss 11 pin harness.
