  In this paper, we study the Kummer pairing associated with formal Drinfeld
modules having stable reduction of height one. We give an explicit description
of the pairing \`a la Kolyvagin, in terms of the logarithm of the formal
Drinfeld module, a certain derivation, torsion points and the trace. The
results obtained give a generalization of the results of Angl\`es proved for
Carlitz modules, and of Bars and Longhi proved for sign-normalized rank one
Drinfeld modules. It also presents an extension of our previous formulas to
arbitrary finite extensions of loca fields containing enough torsion points.
