1990–1992 Chevy Camaro Speedometer Circuit Board Repair Kit (110 MPH & 145 MPH)

DIY parts kit to repair a non-working or intermittent speedometer/odometer by replacing the speedometer circuit board.

Fits 1990, 1991, 1992 Chevrolet Camaro and works with both 110 MPH and 145 MPH speedometers.

Key Features

• Fits 1990–1992 Camaro 110 MPH and 145 MPH speedometer clusters
• Includes a new PCB plus common failure components (capacitors, resistors, diode, crystal)
• Includes odometer motor driver IC and odometer harness plug
• Step-by-step instructions included

What’s Included

• New speedometer circuit board (PCB)
• New electronic components: resistors, capacitors, diode, crystal oscillator, odometer motor driver IC (integrated circuit)
• New odometer wiring harness plug (for early-style plug conversions)
• Step-by-step installation instructions

Installation Requirements

• You must be able to de-solder and solder components
• You will transfer two IC chips from your original board to the new PCB
• If your odometer wire harness has the early-style odometer plug, you’ll replace it with the included plug

FAQs

I replaced a capacitor and/or resistor and it still doesn’t work. Will this kit fix it?
Speedometer operation depends on multiple components working together, not just a single capacitor or resistor. When one part fails, it’s common for other components on the PCB to be stressed or damaged as well, which is why a “one-part” repair discussed on forums doesn’t always restore operation. If the PCB is the root cause of the problem and your two original IC chips are not damaged, this kit typically resolves the issue. If the issue is outside the PCB, or if the original IC chips have been damaged, the kit may not correct the problem.

Will this work for 145 MPH speedometers?
Yes. The PCB is the same for 110 MPH and 145 MPH applications. The difference is in the calibration/logic of the ICs you transfer.

Are all three IC chips available new?
No. GM used multiple versions of the two firmware/calibration IC chips over the years. Those two chips are not available new, so the correct ones must be transferred from your original board to ensure proper operation/calibration. The third IC is included with the kit.
