Hey Mark,
I also have a Sun tach that I will be installing in my truck some day. It
is the same transmitter as you have. Unfortunately the paper that is glued
under the batteries are almost all gone and I cannot read the numbers. Of
course I have no batteries in mine so I don't know the number of the old
ones. That's right, I said batteries. Mine has a place for a battery on
each end of the box. If you come up with a number for this transmitter,
please let me know.
Thanks,
Jim V.
