Restore full-featured RV control center function with the KIB M-Series Monitor Panel — Sierra Custom Interiors OEM (Model M18-2-145SC). Genuine KIB 12V DC monitor panel — the RV control center that monitors tank levels, battery voltage, and generator status, plus controls the water pump, electric/LP water heater, and generator start/stop. Custom-branded for Sierra Custom Interiors — meaningful for owners of Sierra-built RVs restoring their original OEM panel.
⭐ Sierra Custom Interiors OEM — Direct-Fit Restoration
Standout feature: this monitor panel is custom-branded for Sierra Custom Interiors — the original OEM configuration for RVs built with Sierra interiors. Meaningful for buyers restoring their coach to factory appearance rather than substituting a generic aftermarket monitor.
⭐ Full-Featured Control Center — What This Panel Does
Tank Level Monitoring (5-position, push-button):
- BATTERY — battery voltage level
- FRESH — fresh water tank
- BLACK — black water (sewage) tank
- GREY1 — first grey water tank
- GREY2 — second grey water tank (meaningful — dual grey tank capability)
Level Display (LED column): FULL / 2/3 / 1/3 / EMPTY — press and hold any tank button to illuminate current level.
System Switches (lighted rocker):
- WATER PUMP — 12V water pump control (red-lit)
- ELECTRIC WATER HEATER — 120V AC electric element control (red-lit)
- LP GAS WATER HEATER — LP gas burner control (red-lit)
Generator Control:
- GENERATOR START/STOP momentary rocker switch
- ENM hour meter — tracks generator run time in tenths of hours (HOURS 1/10)
- GENERATOR status LED — indicates when generator is active
Fault Indicator:
- HTR FAULT LED — indicates water heater fault condition
⭐ Dual Grey Tank Capability — Standout Feature
Meaningful differentiator vs standard 3-tank KIB monitors: this M18-2-145SC monitors TWO grey water tanks (GREY1 + GREY2) — meaningful for RVs with separate galley and shower grey systems, or larger coaches with dual grey capacity.
⭐ Integrated Generator Hour Meter
Standout feature vs standard monitor panels: built-in ENM hour meter tracks total generator run time. Meaningful for:
- Scheduled maintenance intervals (oil changes, service milestones)
- Warranty / usage documentation
- Resale documentation
How It Works
Standard KIB M-series operation:
- Tank check: Press and hold the tank button (Fresh / Black / Grey1 / Grey2 / Battery) to illuminate the LED level indicator
- Water pump / heater / generator: Flip the corresponding lighted rocker switch to activate — light indicates on-state
- Generator start: Press START (top) momentarily; STOP (bottom) to shut down
- Power draw: Minimal — the panel only draws current when a button is depressed or a switch is active
Complete Wiring Harness Included
Panel ships with the complete pre-terminated wiring harness — multi-connector molex plugs for tank sensors, accessory switch pigtails, and battery/ground leads with quick-disconnect terminals. Meaningful for direct replacement of a failed unit without cutting or splicing.
Common Troubleshooting Reference
Before assuming panel failure, verify these common issues:
- No lights / no power: Verify 12V DC positive (red, B+) and negative ground (white) wires are securely connected to the rear wiring harness
- False tank readings (permanently "full" or non-empty): Mineral buildup or residue inside the holding tanks can bridge the tank probes — flush/clean tanks first before replacing the monitor

⚠️ Professional Installation Recommended
Installation involves 12V DC electrical wiring, multi-connector harness integration, and interfacing with tank sensor probes, water pump, water heater, and generator control circuits. Installation should be performed by a qualified RV service technician unless you have prior experience with RV monitor panel replacement.
