Made my own spa side remote for EasyTouch system from simple buttons kit I got on Amazon under $20, works great. I want to add an LED light that will light up when SPA is on. Does anyone know if the orange wire on the Spa Side connection on the EasyTouch sends 12v? 5v? Just want to know what LED to buy. I'm not currently at the house (it's a vacation rental) so can't test it for voltage.
