Methods are provided for automatically crimping terminals or connectors to wires wherein the terminals or connectors are provided in strip form and may be of varying sizes, shapes, and pitches. A method according to the present invention includes providing a plurality of terminal connectors, the connectors being secured to a terminal strip in side-by-side relationship with their axes extending laterally from the strip; moving a crimping die on a ram through a working stroke towards, and a return stroke away from, a crimping anvil to crimp an individual terminal connector located therebetween onto a wire during each working stroke of the ram; and indexing the strip between successive crimping operations thereby to locate a next leading connector on the strip between the die and anvil, wherein the strip is indexed by a drive mechanism contacting the strip through pressure-engagement.
