Windshield Washer Pump comes on with trucked parked and engine off

[BGlidewell]

The truck can be parked for a while, then the pump will come on. I have to disconnect the washer motor from the electrical connection to stop the motor even when ignition off. Anyone else seen this?

When I changed mine out on my my 06 I got OEM from Amazon it was a few $$ more but I have not always had good lucky with aftermarket parts and have noticed not all aftermarket parts are 100% complete see like in the below photo

this ended up being resolved by replacing the washer pump. It is actuated by a signal on the buss. That was my clue...
