Seems unlikely to me.  There isn't all that much difference (electrically)
between different LED conversions.

But since I went with the flasher I had before and dummy loads to make it
work right, I don't know for sure.

It _might_ cause the flasher to not work, there must be some minimum load
below which it won't flash.

I'm not sure I follow you here.  But a simple test is to install a temporary
jumper in place of the flasher, linking the green wire (B terminal on the
flasher) to the green/black wire (L terminal).  That should let each lamp
work (with the key on and the control head switch in the appropriate
position) with no reliance on any other lamp.

Or just look for the green/white wires where they join near the LH horn.
Use a test light or DMM to check for voltage on the GW that comes from the
steering box (again, switches on).  If there is nothing there, the problem
is the GW wire or the control head.

BTW, I put a diagram up at https://i.imgur.com/OvngNNl.jpg that shows the
correct turn wiring for a later left-hand steer TR3A.  I've not seen
anywhere else that has it just right (including the Advance Auto Wire
diagram).  The LHS diagram is also on page 48a of the PDF at
