Today we are going to do an install of part number 118248 the T One connector from Tow Ready. It will be installed on our 2006 Toyota Highlander.

Once you get everything out of the way it is pretty clear that this is the plug right here for the harness. So our T connector can plug right into here. Then our ground wire will actually mount to this ground bolt right here. We took our ground bolt out and we will simply install our ground wire here and run it back through there and install it.
