Quickly and easily move your GEN3/GEN4 ECU pins around on the header connectors using this handy tool. You simply remove the white cage surrounding the existing pins on the header connector and insert the tool. You will hear a click indicating the pin location tab has been recessed allowing you to remove the connector pin. We do not recommend removing the pin more than 5 times as the more times the pin location tab is recessed the tab can become weak over time.
