Narrative:

While working with contract maintenance in ZZZ on a MEL deferral of the right engine fuel heat valve. All MEL procedures were complied with except for wiring the position indicator into place to secure the valve. On climb out; crew had high fuel and oil temperature. Crew was unable to control oil temperature and shut the right engine down. Aircraft off landed in ZZZ1. Landing was uneventful.
