  Let $S,T$ be two distinct finite Abelian groups with $|S|=|T|$. A fundamental
theorem of Tutte shows that a graph admits a nowhere-zero $S$-flow if and only
if it admits a nowhere-zero $T$-flow. Jaeger, Linial, Payan and Tarsi in 1992
introduced group connectivity as an extension of flow theory, and they asked
whether such a relation holds for group connectivity analogy. It was negatively
answered by Hu\v{s}ek, Moheln\'{i}kov\'{a} and \v{S}\'{a}mal in 2017 for graphs
with edge-connectivity 2 for the groups $S=\mathbb{Z}_4$ and
$T=\mathbb{Z}_2^2$. In this paper, we extend their results to
$3$-edge-connected graphs (including both cubic and general graphs), which
answers open problems proposed by Hu\v{s}ek, Moheln\'{i}kov\'{a} and
\v{S}\'{a}mal(2017) and Lai, Li, Shao and Zhan(2011). Combining some previous
results, this characterizes all the equivalence of group connectivity under
$3$-edge-connectivity, showing that every $3$-edge-connected $S$-connected
graph is $T$-connected if and only if $\{S,T\}\neq
\{\mathbb{Z}_4,\mathbb{Z}_2^2\}$.
