This is the rear harness only for the 210/220 Tractors. Comes with our new 56 style Delphi plugs & terminals. Plugs into our new replacement front wiring system for the 210/220. If plugging this rear harness into an original front harness, new male and female plugs and terminals come with this kit to install on the original front harness to mate to our new plugs. This kit moves the system away from the old style Molex pin type connectors to the flat style 56 series Delphi flat male/female connectors and terminals for maximum contact at the plugs. No flickering lights! A little Dielectric grease in the plugs makes these connections superior to what Mother Nature can throw at em'!  Heavier gauge wiring used to carry current to the lamps better.  A quality upgraded rear system!
