RapidHarness is a software solution for designing and documenting wiring harness. My team was looking to start using a better wiring harness documentation system than the EAGLE schematics we used in the past, so we decided to try RapidHarness (disclosure: they provided us a free professional subscription for educational use).
While using RapidHarness over a few months to document several harness designs for my team, I had a chance to play with a number of its features. I was fairly happy with the resulting design printouts, but along the way I found a number of problems, mostly things that slowed me down as I tried to use the software. I would recommend that anyone interested in this software compare alternatives before settling on it.
