Retrofit MK4 tail lights Caddy 2004-2015

The VW Caddy Mk4 tail lights are available in normal red and smoke versions. Tailgate models up to the Caddy4 can use the Caddy4 twin door lights. The Caddy MK4 tailgate has a different shape at the inside upper corner of the light and thus the Caddy MK4 tailgate lights do not fit to previous models 2004-2015.

Wiring
For this you will need a terminal release tool or very small screwdrivers.

Although the Caddy MK4 tail lights use the same plug and socket as the older model, the wiring configuration is different.
