I found the idea of building a harness daunting also. I watched too many pro level videos with concentric twisted looms and race grade quality. I had to remind myself I’m not building a race car. Even a modern 911 does not have that grade of wiring.

If you hire a pro make sure you’ve made all your design decisions before they start. If you’re building it yourself use quality materials - Deutsch connectors with barrel crimps, quality crimps for wire joins, correct wire gauge for use and temp range, same for sheathing and boots. Test each section as you build - for strength and correct electrical continuity.

Take good measurements and build it out on a 4x8 peg board. My friend and I built ours at the same time. He drew and pinned it up on a plywood board with accurate measurements and I used the dinning table. I had to use a spreadsheet to track my continuity pin outs and wire colours - he just wrote it on the board. There’s no contest which one looks and fits better. Don’t use the dinner table even if your wife is a trooper.
