Attempting to disconnect the DRLs incorrectly can lead to:
* Damage to the BCM: Incorrect wiring can fry the BCM, a very expensive component to replace.
* Other electrical issues: You could inadvertently disrupt other electrical systems in your vehicle.
* Safety hazards: Driving without lights, even during the day, is extremely unsafe.
Instead of disconnecting the DRLs, consider these safer alternatives:
* Leaving them on: DRLs significantly improve your visibility to other drivers, especially in inclement weather. This is the safest option.
* Using a switch: An experienced auto electrician could install a switch to manually turn the DRLs on and off. This is the safest way to disable them if you *must* disable them, but it will require professional installation.
In short: Unless you're a qualified auto electrician comfortable working with the vehicle's BCM and wiring diagrams, do not attempt to disconnect the DRLs. The risks outweigh the benefits. If you're concerned about a specific issue, consult a qualified mechanic.
