How I added EGR wiring to mine, was to use wires from another factory PCM connector, so the terminals were already crimped on. The are pull to seat, so the entire length of the wire has to run through the PCM connector. Then splice on the EGR connector at the proper distance and done. https://ck5.com/forums/threads/quadrasteer-8-1l-suburban-tow-rig.339146/post-4074931.
