99 ZR 700: Tether???

Did the 99 ZR 700 have a tether option from the factory? I have looked at a bunch of parts diagrams I do not see what I have on my new to me 99 zr700 console. Check out the attached image. Purple and brown wires run to that part, which are typically kill switch colors. What I don't understand is the 99 zr700 is an open ignition, so putting a tether in that part seems like it would kill the ignition (completing the circuit). Tracing the purple and brown wires it does look like it goes to the factory wiring harness, not something that someone spliced in.
