The present disclosure relates to electrical connectors and to header systems having such connectors. In one embodiment an electrical connector also known as a header can have two aligning and locating pegs for cooperating with alignment holes of the housing of a control module to accurately and precisely position header in a respective bay of the control module. The pegs of each header can have either unique cross-sectional shapes which can be reflected in respective alignment holes of housing, or can be uniquely positioned on the header which positioning is matched on the holes of the housing to permit each header to be accurately and precisely seated along the x-axis and the y-axis in only one bay and in only a desired front back orientation, or both. In this fashion, the terminals of the header, including its pins, are in position to engage openings in a PCB or other connector. The pegs can also include ribs to capture the housing and prevent vertical or z-axis movement of the header relative to the housing. Retaining the desired vertical position can result in precise placement of the terminals along the z-axis for engagement with respective PCB. Each header can include a trough system to receive overflow of adhesive used to secure the header to the housing.
