Brink Direct Fit Wiring Harness Solution for your BMW X3, X4 and iX3

The Brink 13-Pin Direct Fit Wiring Harness (BR-703574) is a high-specification electrical kit specifically engineered for the BMW X3 (G01), X4 (G02), and the fully electric iX3 (G08). This kit is the updated replacement for the BR-703524, offering superior integration with modern BMW electronic systems.

Key Features:

  • OEM Connectors: Utilizes vehicle-specific "plug-and-play" connectors that match BMW's factory wiring for a secure installation without cutting or splicing.
  • Trailer Stability Program (TSP) Support: Fully integrates with your BMW’s safety systems to help correct trailer sway by automatically adjusting brakes and engine power when a trailer is detected.
  • CAN Bus Integration: Communicates directly with the vehicle's data network to manage complex towing functions and ensure your BMW's warranty remains protected.
  • Automatic Activation: Designed with "Automatic Programming" to activate towing features within the vehicle's computer systems seamlessly.
  • Full LED Compatibility: Works perfectly with trailers and bike carriers equipped with LED lights, preventing dashboard error messages or hyper-flashing.
  • Smart Sensor Management: Automatically deactivates rear parking sensors and disconnects rear fog lights on the vehicle while towing to prevent interference.
  • Power Supply Included: This 13-pin kit includes a steady plus (Pin 9) power supply as standard. (Note: Extension kit 764159 is required for ignition-switched power/Pin 10 battery charging).

Note: This kit is suitable for the BMW X3 G01 (08/2017-on), X4 G02 (04/2018-on), and iX3 G08 (09/2020-on). It is the recommended replacement for the older BR-703524 part number.

Please Note: Towbar wiring is a safety-critical item. Due to the high complexity of modern BMW electrical systems and CAN Bus networks, we strongly recommend installation by a professional towbar fitter or vehicle accessory workshop.

  • TSP (Trailer Stability Program): Yes

Very good chair, comfortable and high quality.
Color: Black
I had my doubts, yet after a couple months I really love this chair. Its a very good quality. Comfortable and sturdy. It allows for me to lean back too, which is a big plus! It looks really great and I am glad I purchased this chair. If you are looking, then just buy it because it is as good as it looks in the pictures.

Perfect for my studio
Color: Black
Naught this chair for my bedroom home recording studio. Honestly, I bought it mostly for the look. I just thought it would look great with what I was trying to v to do in the studio. I was very pleasantly surprised to find that’s its much more comfortable than I had assumed. It was easy to assemble. The provided assembly instructions were clear and easy to follow. It took me less than 20 minutes to build it. The build quality is solid. I’m a tall well build dude that weights more than 210 lbs and it takes my weight very well. Great little chair. I recommend it.

Very happy customer!
Color: Cream White, Color: Cream White
This chair is what you are looking for!!! No serious friends, this chair is everything and so incredibly comfortable! I’m so happy with this purchase. The wood accents I believe are actual wood and the PU leather is gorgeous and seriously looks like real leather. The size is perfect for my frame too. I’m a size medium bottom girly and the curve and level of cushion on the seat is so well executed. The rollability of the rollers are fantastic too, not super loud on our wooden floors and a really smooth glide. Im on the search for a rug to go under my desk but man the patience I used to wait to find this chair truly was worth it. A total lesson on patience and biting when you find the right thing. I think it’s pretty sturdy too. But I’ll report back in a few months. At the moment nothing leads me to be suspicious of a less than long life for this chair.

Good product, could improve backrest depth.
Color: Cream White
Comfortable seat. Stylish looking. Works well. Con is that the backrest is too far away, I had to add a lumbar support pillow. I also added a waffle seat for added comfort as I sit all day in the office. Easy to assemble. Color is nice. Feels sturdy. Rocks back, nice feature. Smooth wheels.
