I bought my VX with an aftermarket stereo already installed. The original cd player wasn't connected but still remained in the dash. I had a nasty buzzing sound which I was able to figure out was coming from this relay connected to my tod box under the passenger seat. When I disconnect the relay the TOD check light comes on. It seems the TOD is drawing power from the relay. The 2 red circles indicate where the relay is connected. The black is a ground and the white is connected to the VX's blue TOD wire. I think the original stereo gave power to the TOD and now a relay has to be in place in order for the TOD to get power. I WANT TO DISCONNECT THE RELAY! I've tried everything to make it silent but I CAN"T GET IT TO BE MORE QUIET now matter how much I wrap it up!!! It has to go! I'm planning on installing a new stereo so maybe I can use IT to give power to the TOD instead of the relay. Right now I don't have a stereo installed...
