These harnesses act as a replaceable protective barrier to prevent oil from wicking into the main harness.
If you're replacing the camshaft position sensors or camshaft adjuster magnets on a Mercedes-Benz, you may see these included in our kits. A common issue with a variety of Mercedes is that oil will wick up through the sensors and into the engine harness. Sacrificial harnesses are there to protect the main harness from oil that can potentially wick up through a failed grommet in the sensor. The oil has been known to cause erratic behavior that has led to harness/ECU replacements and additional electrical damage.
If you'd like to know which kits fit your specific vehicle, please enter your vehicle information on fcpeuro.com underneath "Select your Vehicle". Simply enter your Year, Make, Model, Submodel, and applicable trims. Once your car is selected at fcpeuro.com, our catalog is automatically filtered to show parts that fit your specific car.
Once your car is added to the selector, there are a couple of important ways that we advise correct fitment.
The first is the "fitment indicator" shown on the Product Page after selecting a part. This box is below the "add to cart button" and has two states. It will either say " Yes this part fits" or "Part may not fit, click to verify".
Sometimes the green box will be accompanied by extra fitment notes. These notes may be independent of the information gathered by the vehicle selector. IE: VIN-specific options, need to be taken into account when determining overall fitment.
