So, you're saying that when you connect the electrical line from the truck to the trailer, the ABS light on the trailer comes on, even if the key on the truck is turned off???
If so, you got a short on the trailer somewhere. -
No ABS light at back of trailer maybe I not correct say I have always power at 7 way plug (blue wiring).Any time when I disconnect and connect plug to trailer I hear like work ABS in trailer but key stay at my hand truck not working.

Is it causing a problem? You have constant power on the blue wire? correct?

Get a regular 5 pin SAE relay and cut pin 87A off and you will get your intended functionality.QUALITYTRUCK and Nazar Thank this. -
Probably, the center pin was wired hot even when key is off for trailer tracking systems.
