This kit contains specially designed PC boards used on the original and reproduction GNX dash cluster. The HI LH RH PC board uses high brightness blue and green LED's and is designed to fit a triangle section of the dash, between the two Tach and Speedometer gages. The "idiot light" telltale is designed to fit directly into the factory OEM telltale housing without modification, and contains high brightness white LED's - two for each indicator section - and also includes the ALT load resistor to ensure alternator field current.
