powerline 2000 energy management system

I need to replace my Powerline 2000 Energy Management System circuit board due to a connector that has broken away from the back of the circuit board. Cannot be resoldered..
Part number of the circuit Board #00-00757-000 (27404). This is the nomenclature on the back of the circuit board.
No luck on searching the internet.
Mobility RV states that I must upgrade to a whole new replacement kit ($426.00).
Does anyone have any info that may direct me to a less expensive option?
Thanks
