Update: for anyone else who runs into this problem, I located an easy solution. No cutting of wires or relay wiring harness required... plug and play!
Took a shot on this and it works perfectly. Sends the required current/signal back to the computer/switch. Time will tell if it sends too much current back to burn out the switch, but, it is designed for similar applications.
