Borg Warner is the manufacturer of the TOD system, not an amp. It was mentioned in earlier threads on this site that to rig up a system to turn the TOD on and off it involved cutting the light blue wire coming from the TOD computer under the passenger seat. As was earlier theorized, I think the previous owner of your VX had installed a TOD cut off switch. You can go to Tone's site linked from this site and download the workshop manual, which has electrical diagrams. It may be a whole lot easier to just take the relay to an electronics place to match it up, and then hook it back up as it was using a new (and non-buzzing) relay. Good luck, and let us know how it turns out!
