Part #: CH78OE

Classic Instruments is pleased to release an all-new 1978-'88 Chevy G-Body direct-fit package. It is an all-electric cluster featuring a speedometer, tachometer, clock, and fuel, oil, temp, and volt gauges in an OE style; available either with or without overdrive. Hybrid LED Lighting offers the feel of the original perimeter lighting and the visual benefits of back-lighting: even illumination and clear nighttime readability. Turn signals and high beam indicators are in the original locations and the kit includes new check engine and high beam sockets with LED bulbs. Additional indicator bulbs are available for purchase. The kit also includes a wiring harness, push-button speedometer calibration for ease of setup, a new acrylic lens, and built-in ECM signal filter switch. Save space with Classic Instruments' Zeus Speedometer Technology built-in, meaning the cluster requires no external control boxes and works directly with ECM or VSS signals. The fuel gauge is programmable for many ohm ranges with a selector switch on the back of the cluster, meaning the fuel gauge will work with the stock sending unit, any other factory sending units, or any Classic Instruments fuel sending unit. All other necessary sending units are included in a Classic Instruments GM sending unit kit. Install using customers' existing diffuser.

Features:

  • All-electric cluster for ease of programming and installation
  • OE Style to mimic original gauge cluster look
  • Hybrid lighting to match the original styling and perimeter lighting and improve visibility with backlighting
  • Includes new check engine & high beam sockets with LED bulbs to replace original and provide power from the gauge circuit board
  • Includes wiring harness & push-button calibration for programming and ease of installation
  • Built-in ECM signal filter switch to remove signal noise for smoother speedometer operation
  • Built-in Zeus Speedometer Technology, no external control boxes needed and will work with any available speed signals
