I'm installing a Narva light bar onto my 2010 XC60, as I'm wanting some brighter light on country roads at night. I already have the light bar and a store-bought wiring harness, and have watched a few videos of different light installations. I'm confident I can do it once I get going, and will enjoy the learning experience, but others have expressed concerns it will damage the car's electronics. Does anyone have any tips/suggestions? Unsure whether to just do it, or wait until I can afford to pay an auto electrician to install it (quoted ~$350). Cheers
