*" What Kees says flies in the face of both Moss's (slightly inarticulate)
instructions as well as the consensus of the group"* Quelle surprise !!
Actually, just to clear up the terminology, the resistors are required
between the green with white tracer wire (21) and ground on both right side
lamps and between the green with red tracer wire (18) and ground on both
left side lamps.
The important terminology is that these resistors *parallel* the turn/brake
light filaments to increase the current flow to the 3.2 amps required to
make the 42 watt thermal flasher unit operate as designed.
My middle name is "pedantic" :-)
