This is the rear harness only for the 210/220 Tractors. Comes with our new 56 style Aptiv/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 upgraded plugs. This kit moves the system away from the old style Molex pin type connectors to the flat style 56 series Aptiv/Delphi flat male/female connectors and terminals for maximum contact at the plugs. No flickering lights! No intermitten power issues! A little Dielectric grease in the plugs makes these connections superior to what Mother Nature can throw at em'!  Heavier gauge "tinned" Marine wiring improves current to the lamps better.  A quality upgraded rear system that matches our "knock yer' socks off" front wiring system! Don't guess. Get the best!  B&B Custom Circuits wiring systems for longevity, reliability, & custom aesthetics.
