For the cyrix-ct 120, it says:
"In order to prevent unexpected operation during installation or when one battery has been disconnected, the Cyrix-ct 12/24 will not close if the voltage on one of the two battery connections is lower than 2 V (12 V battery) or 4 V (24 V battery).
My trailer has a wireless brake controller in between the 7 pin connector and the domestic battery, and goes into sleep mode preventing the domestic battery from sending/receiving any power through the 7 pin. Because the cyrix never sees >2v on the trailer side while the brake controller is in sleep mode, the cyrix never activates. Is there a way to disable the <2v feature, or is there a way to get it work given the domestic battery side may be in ”sleep" mode? Currently, it fails to work in my setup due to the wireless brake controller going into sleep mode.
