A replaceable unit for an electrophotographic image forming device according to one example embodiment includes an electrical contact positioned on a first side of a housing of the replaceable unit for contacting an electrical contact in the image forming device. A guide on the first side of the housing is positioned closer to a front of the housing than the electrical contact and leads rearward toward the electrical contact. The guide includes an inside surface that faces inward sideways toward a second side of the housing. At least a portion of the inside surface is angled inward sideways from front to rear permitting contact between the inside surface and an electrical connector in the image forming device to draw the electrical connector in the image forming device inward sideways relative to the replaceable unit during insertion of the replaceable unit into the image forming device.
