If you are getting a no trailer connected warning on your Tekonsha Prodigy P3 # 90195 you may have a corroded or dirty connector which is hampering the connection. Check the vehicle and trailer plug to see if there is any type of corrosion or dirt built up that may be hampering its functionality and clean if necessary.

A bad ground somewhere is also a possibility so you'll need to thoroughly check your grounds to see if they are secure and make sure the ground wires are attached to bare metal surfaces and free of any paint, dirt or corrosion. I have also attached some help articles on testing and troubleshooting brake controllers for you to check out which should be useful.
