[QUOTE="GordoJay, post: 1592154, member: 39584"] You're not planning to use it in the same way as [USER=31547]@Just_in_time[/USER], so you probably don't need such a robust diode. If you choose a diode with a forward current rating at least double the maximum coil current of your relay, you should be fine. I'd still want more than a 12V reverse breakdown voltage, but ~100V is common and cheap. Choose a relay with the lowest coil current possible so that you reduce the chances of bricking your BCM.
