Complete lack of start up.

[Jules-C]

Just splicing the wires together will put a rigid section where the loom flexes with the steering which will possibly end up with the same problem again unless the loom can be rerouted so it flexes on another section away from the repair.

Alternatively replace a longer length of the broken wire so it's a bit of new wire that is doing the bending but this means two splices instead of one.
