Controls Connectors & Wire Harnessing

General

This page is meant to detail all of the connectors needed for the controls system to run, both on our test bench or in the car (production). Noted below for each harness are the relevant connectors as well as the pin-to-pin connections.

LV Harnessing TODO:

  • 3 button harnesses

  • 2 three-position switch harnesses

  • 1 two-position switch harness

  • 1 six-position switch harness

  • Accelerator pedal harness

  • Brake pedal button harness

    Lights:

  • 2 daytime running light harnesses


  • Front turn indicators

  • Side marker turn indicators

  • Rear turn indicators


  • Rear brake lights

  • High mounted center brake light

HV Harnessing TODO:

  • O-ring to O-ring connector from Motor Precharge Bypass Contactor → Motor Controller

CarCAN Harness

Note: we have two CarCAN connectors on our board, although Controls is set up as a endpoint of the CAN bus so there will likely be a terminating resistor on one of the connectors. For the test harness, it would still be nice to have two CarCAN harnesses in case we are set up in between two other nodes.

Pedal Test Harness (Simboard)

Note: We have yet to figure out production harnessing yet. For now, Simboard harnesses are documented. We require one harness for the brake pedal and one for the accelerator pedal.
