Reproduction Of Original Printed Circuit Located Behind Dash Carrier For Cars Without Gauges (Rectangle Speedometer) Also Fits 1970-1972 El Camino And Monte Carlo Without Factory Gauges Correct Plastic Unit With Flat Copper Photo Etched Wiring Replaces Commonly Burned Or Broken Originals Requires 17 P/N 651129-Sold Separately Essential For Proper Gauge And Dash Light Operation NOTE: If you are unsure that your Chevelle has factory gauges or warning lights, you can simply match up the GM number stamped in the copper opening of your original printed circuit. This printed circuit is a reproduction of GM 8901486 After 1969, all 1970, 1971, 1972 Chevelles were equipped from the factory with printed circuits behind the instrument cluster instead of a harness to operate the gauges and lights. Not only was it more cost effective for the factory to use a Chevelle printed circuit, but it saves space, weight and reduces the ?rats nest? of wires typically found behind your cluster. Your 1970, 1971, 1972 Chevelles printed circuit is simply a piece of plastic with conductive copper material embedded in it. Unlike solid hard computer printed circuit boards, these boards are flexible, translucent plastic sheets which operate in the same fashion by conducting electricity to the different dashboard functions. This Chevelle printed circuit can act as a fusible link when using the wrong fuses in your fuse block leading to damaging and costly breaks in the circuit. If your gauges fail or the instrument lighting seems abnormally dim, your Chevelle printed circuit may have gone bad. To easily check this pull your printed circuit and hold it up to a light, you should be able to easily see the break. Be careful your old flexible plastic board might be brittle and rough handling may lead to more substantial damage. If you don?t see yours listed, make sure you let us know. We should be able to get it!
