I installed towing mirrors to my truck. I thought I would be able to just plug them in turn signal along with lamp would work. I can still control moving the mirror from the switches in the truck but can’t seem to figure out why the turn signal or the LED light won’t work.

Most likely a computer will have to be updated / reprogrammed at the dealership. This is common now for added-on equipment that was a factory option. Adding fog lights is another one. The Body Computer must be reprogrammed to know fog lights are on the vehicle before it will try to control them.
