Dashboard PCB for 1967-1972 Chevy GMC C10 K10 – Instrument Cluster Circuit Board Without Tachometer – Replaces OEM 6290458 – FR-4 Fiberglass Upgrade – Fix Dead Gauges & Flickering Lights

Premium Dashboard Printed Circuit Board (PCB) for 1967-1972 Chevy & GMC TrucksSpecifically for Standard Instrument Clusters WITHOUT Factory TachometerReplaces OEM Part # 6290458Restore the functionality and reliability of your classic truck's instrument cluster with our Heavy-Duty Replacement Circuit Board. Designed specifically for 1967-1972 Chevrolet and GMC C/K Series trucks (C10, K10, Blazer, etc.) equipped with the standard gauge cluster (NO Tachometer), this board is the direct solution to the electrical gremlins plaguing 50+ year-old dashes.🚨 CRITICAL COMPATIBILITY CHECK:✅ FITS: Standard instrument clusters that DO NOT have a tachometer gauge. These clusters typically show only Speedometer, Fuel, Temperature, Oil Pressure, and Warning Lights. Replaces OEM Part #6290458.❌ DOES NOT FIT: Instrument clusters WITH a tachometer. If your dash includes a tachometer gauge, you need part #6290459. Installing the wrong board will result in missing connections for the tach. Please verify your cluster type before purchasing.Why Replace Your Original Board?The original GM circuit boards were made from phenolic resin, which becomes extremely brittle over decades of heat cycles and vibration. Common failure symptoms include:Fuel, Temperature, or Oil Pressure gauges giving incorrect readings or failing completely.Speedometer illumination flickering or staying dark.Indicator lights (High Beam, Turn Signals, Brake, Gen) working intermittently.Hairline cracks in the board breaking the electrical continuity between the plug and the gauges.Erratic gauge movement due to poor grounding traces.🌟 Superior Engineering & Materials:Unlike the fragile original, our replacement board is manufactured using modern FR-4 Fiberglass substrate.Heat & Vibration Resistant: Will not crack or warp under dashboard heat, even in hot climates.Enhanced Conductivity: Features heavier gauge copper traces with a protective solder mask to prevent oxidation and ensure consistent signal flow.Precision Etched: Computer-controlled manufacturing ensures exact trace alignment for perfect gauge calibration.🔧 Installation Overview:This is a component replacement, not a complete cluster assembly.Remove Cluster: Carefully remove the instrument cluster bezel and assembly from the dashboard.Disassemble: Remove the rear housing cover. Carefully unclip the original bulbs, bulb sockets, and wiring connector.Transfer Components: Gently remove your original gauges and needles from the old board. Pro Tip: Mark needle positions with a pencil before removal to aid in recalibration.Install New Board: Place your original components onto the new FR-4 board. The mounting holes and trace layout are identical to OEM.Reassemble: Reattach bulbs, sockets, and the main wiring harness plug. Reinstall the cluster into the dash.Test: Verify all gauges and lights function correctly before finalizing trim installation.📦 Package Includes:1 x Dashboard Printed Circuit Board (PCB) - FR-4 Fiberglass(Note: Gauges, needles, lenses, bulbs, screws, and housing are NOT included. Must reuse original components.)✅ Vehicle Compatibility List:Years: 1967, 1968, 1969, 1970, 1971, 1972Makes: Chevrolet, GMCModels:C10, C20, C30 (Pickup)K10, K20, K30 (4x4 Pickup)Blazer / JimmySuburbanRequirement: Must be equipped with the Standard Cluster (NO Tachometer).⚠️ Important Technical Notes:Gauge Calibration: While the board restores electrical connectivity, mechanical gauge accuracy depends on the condition of your original gauge units. If gauges still read incorrectly after installation, the gauge units themselves may need rebuilding.Grounding: Ensure the cluster housing is properly grounded to the vehicle chassis, as some gauges rely on the housing for their ground path.Bulb Sockets: Original bulb sockets can become brittle. Inspect them during installation and replace if necessary to ensure proper lighting.Don't let a cracked $35 circuit board ruin the drivability of your restored classic. Upgrade to a permanent, reliable solution today.
