The ZCI Zero-Contact Interface 4-Pole Wiring Harness Kit # 119250KIT is a universal-fit wiring harness that can work on almost any vehicle without need to cut into the vehicle wiring. This enables it to be moved from one vehicle to another as needed and makes it the ideal choice for a leased vehicle.

The written instructions detail the specific installation checks and steps required to identify the vehicle wires to be used for clamp-on installation of this kit's electro-magnetic sensors. Since we have not yet had your exact 328ix 3-Series vehicle here for an installation you can refer to any of the other BMW videos for general guidance but you will follow the written instructions for your actual install steps. It is important to follow the exact sequence of steps outlined in the linked instructions.

Based on my review of your car's taillight set-up you will use the wiring code for multiplexed wiring, either BT or BTT. My contact at Tekonsha confirmed. You will use the included tester to determine which wiring set-up you have.
