Recently purchased this automobile. With 187,000 miles, it is reasonable to presume that all issues related to the eco wiring have been resolved; nonetheless, a verification will be conducted. The turn signal issue has been resolved; everything is functioning properly again. Continuously perplexed by the fuel gauge and brake pedal. There is undoubtedly no electrical connection between the two; nonetheless, when using the brake pedal, the gauge immediately drops to zero. I can tolerate it, but I am interested if others have had similar issue.
What is the most accessible location to investigate ECO electrical issues?
