After 1969, all 1975, 1976, 1977 GMC and Chevy El Caminos 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 1975, 1976, 1977 El Caminos 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 1975, 1976, 1977 GMC Sprint or El Camino 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 printed circuit. If your GMC or El Camino gauges fail or the instrument lighting seems abnormally dim, your El Camino printed circuit may have gone bad. To easily check this pull your El Camino 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. The El Camino Store has sold thousands of 1975, 1976, 1977 El Camino printed circuits over the years and has worked closely with a manufacturer to make sure all possible combinations of Sprint or El Camino printed circuits are available for your classic El Camino. If you don’t see yours listed, make sure you let us know. We should be able to get it!
