After searching it appears my intermittent radio problem is due to the relay not receiving the +12vdc from the radio. I think I've located the relay in the passenger side, underneath the dash, but I can't tell for sure.
Can anyone who has done this confirm the color codes? I was planning on just crossing the +12vdc switched power to the relay as well, so the speakers are always energized when the ignition is on.
