Fan Switch Harness MGB 1977 to 1980 to (c)511290

This is the short wiring harness that takes a lot of abuse over the years with lots of heat from the engine compartment and lots of power traveling through it when the fans are running at full tilt. The wiring will break down and short out and sometimes wipes out the radiator sensor. So if your sensor goes bad to turn on the fans its a good idea to change this harness to.
