Tapped into each cargo light in the bed of the truck. Ran 4 3 lamp LEDs down each side and tied them directly to the cargo light wiring in the bed. I wanted them to come on when cargo switch pressed, and when unlocking the truck. Works great....until the truck is running. If the truck is running, all of the cargo lights just blink if enabled. This does not occur if the truck is not running. Any guidance would be appreciated.
