Headlight wiring feeds

Does anyone have any suggestions as to the proper installation of the wiring harness as it feeds the headlight bucket? The issue I see is the excessive flexing of the covered harness where it enters the headlight bucket when you turn the wheel. Do I just feed the covered wires inside or strip back the harness covering and just feed the wires? It just seems like there is way to much stretching and pulling going on with the whole cable bundle feeding through.
