Connection definition

Integral, sealed, motorsport connectors:

• Connector A 66-way
• Connector B 114-way
• Connector C 114-way

Environmental

• Splash resistant to standard motorsport fluids
• Lids sealed with o-rings
• Maximum humidity 100%
• Minimum operating temperature 0°C
• Internal temperature not to exceed 70°C as measured by internal diagnostic sensors
• Adequate forced-air cooling must be applied to ensure the internal operating temperature remains within specified limits
