constant cold alarm narrowed to VRO tank

[LEASEGUY]

directly where the two wires go into the VRO pickup tube housing, moving the wires starts and stops the alarm, with the housing off the tank and in hand I removed two screws from the underside but it wont seperate to reveal what these two wires connect to.......how do I open this section???????
anyone please

these two wires are the low oil signal wites for the vro tank, one is a ground the other is a signal to the alarm. when the alarm wire is grounded alarm gos off,
check for water at bottom of vro tank this can cause the signal to ground or check for tan wire to be grounded if all is good replace pick-up tube and purge oil line
