Retrofitting the L663 Blind Spot System: A Step-by-Step Guide

Enhance your vehicle’s safety by retrofitting the L663 Blind Spot System. This guide provides a detailed walkthrough for integrating this advanced feature, commonly found in newer models, into your car. This modification involves installing new mirror components, wiring, and system modules, followed by software programming.

Parts Identification for L663 Blind Spot System Retrofit

Before commencing the retrofit, ensure you have all the necessary components. Identifying the correct spare parts is crucial for a successful installation of the L663 Blind Spot System.

  • Right Mirror Assembly (Blind Spot, Chromic, Heated): LR129705 (used, approximately 100 Euro). This mirror includes the blind spot indicator and heating elements.
  • Left Mirror Assembly (Blind Spot, Chromic, Heated): LR129699 (used, approximately 100 Euro). Similar to the right mirror, this unit incorporates blind spot and heating functionalities.
  • SODR and SODL Modules: LR129341, LR159593 (new or used). These modules are interchangeable with those from other Land Rover models, including L8b2-14f-152bx from Defenders. Programming is required regardless of the source.

To connect the new mirror assemblies, you will need a specific cable, often available on eBay, to interface the mirrors with the door connectors.

Wiring the Blind Spot System

For the blind spot system connection, utilize pin connector 41841145.

  • Red wire: Connect to pin 12 of the door connector.
  • Orange wire: Connect to pin 11 of the door connector.
  • Ground: Connect to a black ground wire within the mirror assembly.
  • Chromic Function: Purple and blue wires connect to the two-pin connector in the mirror. Connectors for this purpose can be sourced online.

Rear Sensor Installation and Wiring

The rear part of the installation requires connecting two CAN H wires (blue and blue/green). These can be tapped from the side connector on the central console, specifically connector C32h1.

A dedicated power supply is needed, drawn from the passenger junction box C2BP02H-5, located under the top case. Use the white/green wire at pin 5 of this connector.

All these wires must be routed to the rear of the vehicle. This necessitates removing the passenger seat and the rear passenger side panel to access the area near the suspension compressor. In this rear location, you will also connect a ground wire and wire the rear sensors for the L663 Blind Spot System.

To install the rear sensors, removal of the rear bumper is required. Refer to online video tutorials for detailed instructions on bumper removal. The modules can be mounted using joints, eliminating the need for screws. Connector and pin diagrams are available for precise connections.

Software Programming and System Configuration

Once the physical installation is complete, the SODR and SODL modules must be programmed. This involves setting the correct Car Configuration File (CCF). After modifying the CCF, it is essential to perform an alignment to the central configuration to prevent emergency brake errors.

The following CCF parameters need adjustment:

  • EUC-037 Blind Spot Information System: Set to “Blind Spot Information System With Radar Direct LED”.
  • MultiCAN-794 Rear Corner Radars: Set to “Rear corner radars fitted”.
  • MultiCAN-723 RCTA Configuration: Set to “Motion based alert”.
