  We present a new implementation of the hybrid antisymmetrized Coupled
Channels (haCC) method in the framework of the tRecX [A. Scrinzi, Comp. Phys.
Comm., 270:108146, 2022.]. The method represents atomic and molecular
multi-electron functions by combining CI functions, Gaussian molecular
orbitals, and a numerical single-electron basis. It is suitable for describing
high harmonic generation and the strong-field dynamics of ionization. Fully
differential photo\-emission spectra are computed by the tSurff method. The
theoretical background of haCC is outlined and key improvements compared to its
original formulation are highlighted. We discuss control of over-completeness
resulting from the joint use of the numerical basis and Gaussian molecular
orbitals by pseudo-inverses based on the Woodbury formula. Further new features
of this tRecX release are the iSurff method, new input features, and the AMOS
gateway interface. The mapping of haCC into the tRecX framework for solving the
time-dependent Schr\"odinger equation is shown. Use, performance, and accuracy
of haCC are discussed on the examples of high-harmonic generation and
strong-field photo-emission by short laser pulses impinging on the Helium atom
and on the linear molecules $N_2$ and $CO$.
