Narrative:

While outside running the aircraft two APU starter generator wires were found to be disconnected. The wires that were disconnected were taped separately to the two larger terminal wires and labeled. After bringing the aircraft back into the hangar I connected the two disconnected terminal wires as they were labeled and taped and torqued them per the amm.I found out when I returned to work that evening the wires were marked incorrectly so I had installed them incorrectly. We would normally install the wires how they are marked. As far as I was aware the operations check was written up separately.
