1976-1982 Chevy-GMC Truck Dash Flexible Circuit Board, Intellitronix

After 1967, all trucks 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 printed circuit, but it saves space, weight and reduces the “rats nest” of wires typically found behind your cluster. Your truck's 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 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 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.  1976-1982 Chevrolet C/K Truck 1976-1982 Chevrolet Blazer 1976-1982 Chevrolet Suburban 1976-1982 GMC C/K Truck 1976-1982 GMC Jimmy 1976-1982 GMC Suburban
