Johnson Controls ( JCI) plans to acquire Borg Instruments, a privately held automobile electronics firm whose clients include BMW, DaimlerChrysler ( DCX) and General Motors ( GM).

The details of the deal, which will be an all-cash transaction, weren't disclosed, but in a statement, Johnson Controls predicted that Borg's sales would grow by 35% each year through 2006.

"For Johnson Controls, Borg Instruments will strengthen our interiors electronics capabilities as well as our technological presence in Europe, and will be the base for the development of our high-end electronic instrument clusters activities," said John M. Barth, the president and chief executive of Johnson Controls. "In addition, we anticipate transferring the Borg technology to the North American and other markets."

Borg, based in Remchingen, Germany, employs 400 workers.

Johnson Controls, a German automotive systems provider, expects the purchase to close this summer and contribute to its earnings in fiscal 2004.
