Trailer Brake Controller stays on even with key out

Just got to wiring up my brake controller and the thing stays on even after i shut the truck off and take the key out... is this normal? I checked for power at the factory plug, just to eliminate the possibility that i wired something wrong, with my multimeter and sure enough there is constant 12v power right at the harness (the one under the dash next to the parking brake).

What gives?

 

My Tekonsha will shut down around 10minutes after the truck is off. Once brake pedal is pressed activating brake lights, it turns on again.

 

Normal, no problem.

 

normal afaik.

my chevy's trailer brake did the same thing.

 

normal for mine

 

yep, normal

 

Same here on my Tekonsha Prodigy P3. That's normal.
