since its not the 5-mode, it doesnt need the third brake light harness so you literally take off the stock ones and plug these in. no wiring from third brake light into the trunk like the 5 mode ones.
It was when vland first released the euro style tailights. They are the first version of the tailights before the 5 mode ones came out so they just light up like stock(no amber or anything/ just red). hope that helps
