There is no Relay. But I believe that the Radio chassis has to have good ground. That can be easily checked with a test light connected to a Positive(+) Source.
Never heard of a external radio relay, but you need to find the radio fuse and check it, you can Google a diagram for the fuse panel, there should be one under the hood and one inside, hope this helps, make sure radio is not dead, and there are 2 power wires, one for memory and one for accessory, both have to to be powered for radio to work, the relay you see could be for a factory amp or antenna booster

You might have cut a wire or it could have broken or disconnected. Try tracing the wiring where you hooked up the trailer you may find one broken or disconnected.
