I have a 03 250 7.3 - i've towed alot w/ this and no problems until tonight. the pigtail will not work i hooked it to 2 different trailers and got no power. i checked the two 20a fuses in panel and they are good. i did hook the 7 pin to a third trailer and it worked fine. can you give me some idea why the pigtail won't work? also, in last few week the overhead console went out don't know if this could be related. thanks for your help

 

What pigtail is it, seven pin to a six round or four flat? Or is it just a seven to seven extension
