OP
I don't think there are any shielded or twisted-pair conductors in a TJ harness. That's the only thing I can think of that would need special consideration. Maybe someone else with more TJ-specific wiring experience will come along and share more info.
The wire appears to be single core stranded. No shielding or twisted pairs. At least not from what I can see where the insulation was ripped from the t-tap
