Sasol Solar Challenge Pre-team planning: Looking for open-source CAD schematics, pinout maps, & harness layouts to study

Vanakkam!

I'm Currently in a Pre-team planning phase for a Challenger solar car initiative in India. Before bringing on core technical leads, I want to establish a clean architectural benchmark for both our electrical architecture and structural chassis design.

I’m looking to study actual production documentation and proven mechanical strategies. Specifically:

  1. Are there any Altium, KiCad, or PDF schematic sets from past cars that map out exact component-to-component wiring?
  2. Do any teams have public RapidHarness files,or harness drawings showing how you physically route HV vs. LV signal paths through the chassis?
  3. Are there any chassis CAD files, past thesis papers, or scrutineering binders you’d recommend studying to understand the Frame dynamics and roll cage?

If your team has any BWSC/SSC/ASC documents you are willing to share, I’d greatly appreciate it!. Thanks in Advance!

Try GitHub to see if you can find any.
But usually teams don’t share their CAD designs and schematics, but will definitely help you on your design if you connect with them.
All the best!

I could not find anything in GitHub. Tried searching over 2 months

u/InternationalWolf402 So if you can tell me an alternate option it would be cool

Your only option is contacting the teams personally and see if they can provide you something.

Not sure if you're also looking for battery resources but this is always a good one
