I have SolidWorks but it’s on my computer that is waiting on a power supply unit from HP. I’m going to use TE connectivity’s software for wire loom design anyways, so hopefully they have schematics built in for this too. TE’s software is more or less an industry standard in professional automotive wiring harness design. It has all their connectors already in the software and I’ll be using DT and DTV series connectors for my wiring harness.
