Easy to install -- price is very high
This harness is quite easily installed and made for a 5 minute replacement of the old factory harness that had some corrosion problems. However, not convinced that the easy of installation justifies the very high price. The aftermarket harnesses are likely just as good.

7PIn worked great on my F-250
It was a easy installation and direct connect for my 1999 F-250, the fuses and relays came in handy as they were needed for the Brake controller to work correctly.

Fits Great and Works Great
I was working on a friends truck, he had bought a used F-250 that had a 4 pin to a six pin to a seven blade adapter. When he hooded up his trailer the brakes would lock up. Buying this ford factory plug to a seven pin adapter fixed all his issues. If your truck has a rigged up hillbilly trailer harness just go ahead and replace it with this product and quit chasing your tail. your life will be so much easier and you can hop in your truck knowing everything works just as it should.
