An electrical connector assembly (100) which includes electrical contacts (10) of the insulation displacement type, an inner housing (20), an outer housing (40), and a strain relief member (50). The assembly (100) is assembled by first securely placing the electrical contacts (10) within the inner housing (20) and then inserting the inner housing (20) into the outer housing (40) so that the electrical contacts (10) can be terminated to wires by using the insulation displacement method of wire termination. The inner housing (20) is fully inserted into outer housing (40), and is then in a fully latched position within the outer housing (40). Strain relief member (50) is then mounted to outer housing (40) and includes an abutment flange (55) for ensuring that the inner housing (20) has been fully inserted within outer housing (40). The wires which are terminated to the contacts (10) will extend around an inner wall (53) of the strain relief (50) and will be laced between retainer walls (58) so that strain relief will be provided to the assembly (100).
