Guideline

The schematic needs to represent all connections, pinouts, and wire paths clearly. Labelling should be consistent. Please follow the guideline below when you draw the harness schematic.

After the harness is made, be sure to use DMM to check continuity on all pins!

Example

We use TinyCAD to draw the harness schematic, see examples below. Other software is also ok as long as the schematic is clear and formatting is consistent.

Battery Splitter Harness Example

JST CAN Harness Example

The double X on the CAN wire pair means the CAN_H and CAN_L wires should be twisted together.
