DETROIT (AP) _ Ford Motor Co. said Tuesday it is splitting its Electrical and Electronics Division into two separate divisions, one for automotive electronics and one for electrical and fuel-handling systems.

''The application of electronics in Ford cars and trucks is expected to grow significantly in importance in the next few years,'' said O.B. Marx III, Ford's Diversified Products Operations director for automotive components.

''At the same time we have major programs under way in electrical and fuel- handling operations. So we chose to separate the electro-mechanical functions from electronics products,'' Marx said.

Frank E. Macher, general manager of the Electrical and Electronics Division, becomes general manager of the new Electronics Division. Robert J. Womac, director of corporate strategy for the old division, becomes general manager of the Electrical and Fuel Handling Division, Ford said.

The 14,800-worker Electronics Division handles all electronics technology and products including powertrain controls, audio systems, instruments and electronically controlled equipment such as anti-lock brakes.

The 6,084-worker Electrical and Fuel Handling Division is responsible for equipment such as alternators, starters, fuel pumps, small motors and ignition products.

The Electronics division has plants in Pennsylvania, Mexico, Ontario, Great Britain and Brazil. The Electrical and Fuel Handling Division has Michigan plants in Rawsonville and Ypsilanti and a plant in Bedford, Ind.
