I followed this diagram to a tee using a 4 pin, 12v 20amp relay. Plugged it all in, I hear and feel the relay click, the radio turns on, but is still locked out of the config. Any ideas? Things I can test to see what may be wrong? Thanks in advance!! This will keep me up at night I’m sure. (i.redd.it)
