Exposed Wiring Connections
This LCF IPR connector has been subjected to water intrusion due to a water tight harness cover. There was a recall to address this concern however any 4.5L Power Stroke is susceptible to this due to it's exposure to the elements. The connector on the IPR must face down and water should be allowed to drain from any protective covering. Packing the connector with dielectric grease is also a good idea.
