Repair connector for the VP44 injection pump. Fault code P1689(no communication between VP44 and ECM) is a common problem when this harness goes bad. Pins in this connector can wear out and not seat properly to VP44 pins. Why replace the entire $1,000.00 engine harness when you can replace the connector?
