Flasher?  W1, C1 and C2 are the terminals on a particular Lucas relay =
used as the electric fan relay for the GT V8, for example, but were used =
for other things on a number of other British makes and marques.  They =
are rectangular.

Are you sure the flasher unit (strictly speaking it's not a relay) goes =
behind the console?  It did on some cars, but on others it was behind =
the dash pushed into a clip screwed to the bulkhead.  2-pin are =
rectangular but smaller than the relays, 3-pin may be cylindrical and =
quite a bit larger.  I'm not aware of a relay inside the cabin on any =
MGB, maybe someone in the past went to replace the flasher unit but =
asked for a relay instead.

The wire colours should be brown to the X terminal on the flasher unit, =
light-green/brown to L to light the lamps at the corners of the car via =
the hazard switch, and light-green/purple on P for the tell-tale on the =
console.  Also the brown comes via an in-line fuse (brown both sides) =
which should be near the flasher unit and is shown as connecting =
directly to it, no bullet connector on the flasher unit side although =
there is a 2-way connector on the supply side.

Problems with some lights flashing and some not, and the indicators not =
working, are usually down to the hazard switch itself.  On most cars it =
is very rarely used and the grease hardens over time to become an =
insulator rather than a lubricant.  Sometimes flipping the switch back =
and fore a few times will get it going again, but I've had to dismantle =
the switch, clean out the old grease and use fresh before it worked =
consistently
