Re: Radiator Fan Override Switch (The Easy Way)

Without 30 connected to ground your override switch will still work. However, your PCM won't be able to turn on your fan. It shouldn't throw a code, but it will definitely contribute to overheating if you don't turn your fan on manually when your engine starts getting hot.
