There was a hazard system that I believe was a dealer
It consisted of a flasher that mounts on the firewall
inbetween the clutch pedal and the kick out vent on
the side, a wiring harness that splices into the connections
to the rod operated turn signal switch and a red knob
switch that attached to the left side bolt that holds
the steering column to the bottom of the dash panel.
You can see the swtich in this photo:
I am sure specter off road would have all of the
parts required to add this to your 45.
