I believe (but could be wrong as I never heard this from Ryan) that Ron Francis was actually who was manufacturing the harnesses to RJM specs anyway. At least after the first few runs, if not all along.
So it was a pretty natural segué for them to start marketing it themselves when RJM closed the doors.
It's not like it's the only game in town of course, but the RJM/Ron Francis Bronco-specific harness is a pretty clean and clever setup.
We also sell our #5920 (
