{"product_id":"classic-instruments-oe-style-g-body-instrument-cluster-ch78oe","title":"Classic Instruments OE Style G-Body Instrument Cluster - CH78OE","description":"Bring your 1978–88 G-Body back to life with an all-electric, OE-style cluster that installs cleanly and reads accurately. This direct-fit package includes a speedometer, tachometer, clock, and fuel, oil, temp, and volt gauges with Hybrid LED Lighting that blends perimeter glow with back-lighting for even illumination and excellent nighttime visibility. Turn signals and high-beam indicators remain in the stock locations to preserve factory ergonomics. The kit ships with a model-specific harness, push-button speedometer calibration, new acrylic lens, and a built-in ECM signal filter switch. Classic Instruments’ ZST™ (Zeus Speedometer Technology) is integrated—no external control boxes—so it works directly with ECM or VSS signals. The fuel gauge features a rear-mounted selector switch to match most factory senders or Classic Instruments senders. Use your existing diffuser for a factory-true finish.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes new check engine \u0026amp; high beam sockets with LED bulbs to replace original and provide power from the gauge circuit board\u003c\/li\u003e\n\u003cli\u003eIncludes wiring harness \u0026amp; push-button calibration for programming and ease of installation\u003c\/li\u003e\n\u003cli\u003eHybrid lighting to match the original styling and perimeter lighting and improve visibility with backlighting\u003c\/li\u003e\n\u003cli\u003eIncludes GM sending unit kit – complete, no separately purchased parts\u003c\/li\u003e\n\u003cli\u003eAll-electric cluster for ease of programming and installation\u003c\/li\u003e\n\u003cli\u003eBuilt-in Zeus Speedometer Technology, no external control boxes needed and will work with any available speed signals\u003c\/li\u003e\n\u003cli\u003eInstalls with existing diffuser for original look\u003c\/li\u003e\n\u003cli\u003eOE Style to mimic original gauge cluster look\u003c\/li\u003e\n\u003cli\u003eBuilt-in ECM signal filter switch to remove signal noise for smoother speedometer operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Classic Instruments","offers":[{"title":"Default Title","offer_id":49690356515054,"sku":"CIN-CH78OE","price":1117.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/bb3319dc05f88d0b311b215c8b9f70840abec08e.jpg?v=1791410060","url":"https:\/\/elmosspeedshop.com\/products\/classic-instruments-oe-style-g-body-instrument-cluster-ch78oe","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
