Classic Instruments - CT88DOE

1988-94 Chevy Truck OBS Instrument

Without gear indicator

The kit also includes: a wiring harness, push-button calibration for ease of setup, and built-in ECM signal filter switch to remove signal noise for smoother speedometer operation. 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. Zeus-Link is available for separate purchase for a direct connection to GM and Holley ECUs. Install using customers’ existing diffuser and lens. This new ’88-’94 OBS Chevy truck cluster from Classic Instruments is proudly made in the USA and can be purchased direct or through any one of its authorized dealers or at holley.com.
