Question about swapping ECUs

[Eddy, Michael]

'Evening...

I'm probably going to sell or trade my '92 Classic, which has a JWT ECU.
I'm thinking of buying a stock ECU from another '92 for cheap to simplify
things if I end up selling my ECU and the car separately.  I can't remember
if there are any compatibility issues I should be concerned about, such as
whether either of the cars has ABS or something.  Can someone in the know
please comment?  Many thanx...
