This harness is designed to fix a very specific issue with the zl1. Due to the black door panels on a zl1 the door lighting is very dim. This harness is a complete plug n play replacement harness, includes hardware for BOTH doors and makes the ambient light much brighter than before, but not too bright and is still dimmable through your factory switch. You have the option of choosing the factory color of ICE BLUE, or changing the color to zl1 red or even krypton green!
Please make sure you choose the correct options for your purchase. This kit includes hardware for BOTH doors. The vertical lighting that goes down the back side of the panel as well as the illuminated trunk switch can all be added or declined in the options before purchase.
