Regarding your order: the option to modify an existing harness is reserved for customers who have a pending order for our CCE Fog Light Conversion Kit. This allows us to modify the harness within the Baja Designs kit before it is fulfilled. If you do not have a kit currently on order, please select the "New Harness" option. Please note that the CCE AUX Switch Harness Upgrade is designed specifically for our CCE Fog Light Conversion Kit using the original Squadron lights. This setup is intended for use with the factory switch and features one (1) input. As the Squadron 2.0 utilizes two (2) inputs, please inquire about the necessary configuration before placing your order. For the upgrade, this must be purchased at same time as your ditch light or fog light conversion with Baja designs lights. We take the harness that Baja Designs provides and modify it to work with the factory AUX switch if you would like a new harness (not purchasing with a set of Baja Designs Lights), please select the new harness option. Most 2023+ GMC Canyon & Chevrolet Colorado models have a factory AUX switch in the center stack. We developed as close to a plug and play kit to utilize this factory AUX switch to utilize and activate this switch to install Fog Light Conversion Kits for your ZR2 or add ditch light brackets to your truck. Kit comes equipped with 2-Pin Weatherpack plugs which are commonly found on Baja Designs Pod Lights.
