<E28> Fried SI Circuit board, where to buy?

[Mark Rich <mrich@xxxxxxxxxxxxx>]

    I wanted the SI lights out, and I believe they will be out for a
while.  I fried the SI circuit board (must have created a bridge
somewhere).  I do remember an earlier post that mentioned the name of a
vendor that supplies this board with Li batteries instead.  Does anyone
have that info, or will I have to fork up the $405 that the dealer
wants?  I would just let it be, but I like everything to work as it
should.  Right now the MPG gauge waltzes into the 40 mpg range, with the
car  standing still, and then returns to zero.
