*"According to an article (with a picture) on John Simms website by Rich
Chysler the BN2 had the flasher unit on the inside face of the firewall"*
Yes that is correct for all 100's Michael. There is a grommet through which
the 2/3 wires pass to connect with the flasher unit. I suspect, as flasher
units were pretty new technology at the time, there was some concern as to
their weather or heat resistance.
