Locker indicator lights question

I just installed the two switch modification to turn my lockers on. The front pump turns on and the indicator light blinks, and then turns on steady when the pump is up to pressure. The rear turns on and the light blinks, but when it is up to pressure the pump quits, but the light still blinks. I can hear the rear pump stop as it comes up to pressure. I hate blinky lights. Any idea where to look first? Doesn't the sensor turn off the pump?

The pumps shut off when they sense they have reach the correct pressure (5psi)

The light is controlled by the computer which uses a sensor (electronics switch) in the diff to tell if the locker is locked or unlocked.

If the light blinks than it means your locker isnt locked, malfunction in the locking system, or the sensor in the diff is bad, or the wirring/computer is bad.

I had a sensor go bad in mine and the locker was working, I could hear the pumps shut off and I could tell the locker was working as I tested it offroad. But the locker light would just keep blinking, Unfortunately to replace the sensor in the diff you have to pull the carrier which can be alot of labor.

Hope that helps.
