Why this guide matters
Choosing between eighteen Hyundai, Kia and Genesis harness photos is the step where most beginners get stuck. The sunnypilot harness finder turns that into three or four taps on your phone while standing at the car. It names the harness to buy, warns about missing wires and tells you when a pin flip is needed.
