Hand held toggled remote from WARN. I had to cut this open to verify leads were still connected, was used on a z3500 winch that failed (not the remote) Eventually replaced entire configuration. Now I have the old winch in parts, and this remote controller. It still works, and merely needs to be heated back together.. I have it as a spare. No wires have been disconnected. All wiring is intact. New or used, these are costly. 20$ and you can have the old winch parts as well. (motor, housing, spool)
