Removed the tail light / plate light wire harnesses from my 04 f250. Have power to plug but not to lights. Anyway, part number off the harness is 4c3t-13a409 aa. Can’t find the harness match on the web. The one I found is similar but the first set doesn’t match (43ct) although the second set does match (13a409). Any help at all is much much appreciated!

 

What is usually done is to locate the break in the harness to the tail lights and insert a splice using shrink connectors. The repair is quick, neat and weather protected. No need to replace the entire harness.

 

Depending on what/where, there are pigtail /connector harness repair available as well..
