Designed to be a drop-in replacement for the JuiceBox Pro 40 with LEDs on the front (UL version). An alternative relay for NON-LED equipped boxes (2016 and prior, some 2017) is available on "the big A" if you search for "Baomain JQX-62F-2C" and ignore the sponsored result. Or, also try searching "B010L02RUO" for a direct link. Be sure to get the 12 volt DC coil relay, not the 220v one.
There is no available replacement for "JuiceBox 2.0" (grey/purple plastic case, large LED strip) that I'm aware of.
For installation, you will need to unclip the pilot signal wire from the original relay connector and insert it into the new one (pressing the release tab with a small flat screwdriver will do the trick - just bend it back afterward).
Ships USPS First Class or Priority, your choice.
