Premade wiring harness - Autosteer - AgOpenGPS

I realized that the bigger the community is it might make sense to look if we could get some premade wiring harnesses in china. I’ve seen a wiring harness made by RTKAgri ( Redirecting ) I tried to make a wiring diagram that I think would fit my needs + exposed all the cables so it’s relatively simple to connect. I’m curious if these lengths / wire sizes are adequate? (I don’t want to use less than 0.5mm2 but I believe 1mm2 should be decent even for 12V motors that sometimes pop the 7.5
