Recommended Electrical Connectors Types.Many of the procedures in this guide will direct you to a specific electrical connector. Use the following to help determine the connector. The "DT" connectors use an orange wedge to lock the pins in place. Ensure that the orange wedge is properly installed.1. Check to make sure all seals are present and properly seated. Check pins and sockets before joining connectors. Verify proper alignment and locations of pins and sockets in each connector.2. Check "DT" connector locking and "HD" connector lock ring. Make sure that the connector is properly locked (you will hear an audible "click") together and that the two mating halves can not be pulled apart.3. DO NOT exceed 2.25 N m (20 lb in) of torque on the ECM connector bolt when connecting the 40 Pin "DRC" connector to the ECM. Make sure the connector bolt is properly tightened.4. Perform 44.5 N (10 pound) pull test on each pin/wire. Each pin and connector should easily withstand the pull test value and remain in the connector body. This test ensures the wire was properly crimped in the pin, and the pin properly inserted in the connector. DO NOT solder pins/wires. Pins should always be crimped onto the wires using the 1U5804 Deutsch Crimp Tool.
