Abstract
A method of manufacturing a control strip for injection valves in plastic fuel lines of an internal combustion engine, comprising forming a conductive preform defining at least two conductive elements initially connected by removable bridges formed of the same material as the conductive elements for controlling said injection valves; embedding said preform in an insulting plastic; removing the bridges between the conductive elements to electrically isolate the conductive elements from each other; and thereafter casting the plastic-embedded and electrically isolated conductive elements into a one-piece control strip which serves as a housing and electrical control strip for the injection valves.
