WTB coralvue smart ATO pump extension cable

[Philt56]

looking for the cable to extend from the ATO reservoir pump to the sensor. Coralvue wants $20 plus another $10 for tax and shipping, hoping to get cheaper if someone has a spare. Either the 2m or 3m is fine.

I also see there are DC extension cables on amazon cheap but not sure about the voltage or plug size that would be compatible with the smart ATO.

Thanks

Phil
