Switch Panel Planning¶
Primary Switch Locations¶
Dash-Mounted Switches - Headlight switch (OEM style or custom) - Wiper/washer switch - Hazard switch - Defrost switch (if equipped) - HVAC blower switch
Center Console Switches - Transfer case mode selector - Aux light switches - Air compressor switch - Diff lock switches (if equipped)
Overhead Console (Optional) - Map lights - Aux light master - Radio controls
Infinitybox Input Mapping¶
See: MASTERCELL_INPUT_MAP.md for complete input assignment table.
Summary: ~30 inputs defined across lighting, ignition, powertrain signals, driver controls, vehicle status, and auxiliary switches. Some inputs pending clarification from Infinitybox (driver door, mirrors).
Wire Routing Strategy¶
Engine Bay¶
Front POWERCELL Location: [ ] Driver fender / [ ] Passenger fender / [ ] Firewall - Considerations: Heat, water intrusion, accessibility - Infinitybox recommendation: Driver inner fender common location
Engine Bay Runs - Battery cables (0/2 AWG) - POWERCELL power feed (4 AWG from battery) - CAN bus to rear POWERCELL (if used) - CAN bus through firewall to MASTERCELL - All lighting outputs from POWERCELL
Firewall Penetration¶
Single grommet strategy recommended: - CAN bus cable (2 wires + shield) - Key-on signal wire - Any additional signal wires - Use weatherproof bulk grommet
Interior¶
MASTERCELL Location: [ ] Under dash / [ ] Behind seat / [ ] Center console - Needs access to all switch inputs - Protected from water/debris
Interior Runs - Switch panel wiring to MASTERCELL - CAN bus from firewall - Gauge cluster connections - Door trigger wires - Rear lighting feeds (if no rear POWERCELL)
Rear of Vehicle¶
Rear POWERCELL (Optional) - Location: Behind seat or in bed - Purpose: Reduces wire runs for rear lights, bed accessories - Connected via CAN bus from front POWERCELL
Grounding Strategy¶
Chassis Grounds¶
- Primary ground: Battery negative to frame (0 AWG)
- Engine ground: Block to frame (2 AWG)
- Body grounds: Cab to frame at multiple points
Infinitybox Grounds¶
- POWERCELL grounds: Heavy gauge to battery negative or chassis
- MASTERCELL ground: To chassis near installation point
- All grounds should be star-pointed to battery negative when possible
