Section 4.6
Servicing DDEC Connectors

Newly released kits make servicing DDEC connectors and terminals easier than ever. Crimp tools are not required for simple factory approved repairs. The connector service kit for DDEC II/III/IV is P/N: 23528593. The connector kits for DDEC IV (2002) is P/N: 23527566. ‪

Additionally, it is recommended that whenever possible, the connector and harness incorporate a “service loop” on sensor connections. To achieve this, the harness should be looped back and tie wrapped to the sensor leaving a 3–inch loop. This size loop has proved to substantially protect the mating connector terminals. See Figure "Connector Service Loop" .‪
