While it would be very dim compared to how we see it from Earth, it would still give much more light to Pluto than Earth gets from the full Moon.

Pluto's perihelion is 29.658 AU. Using the inverse square law, the brightness of the sun would be 1/29.658^2 the brightness seen from the earth, or about 1 / 880.
In terms of magnitude, take the base 10 log of 880 (2.944) and divide by .4 to give 7.36, which is the number of magnitudes difference between Pluto's view and our view. Since the Sun is at magnitude -26.8 from earth, from Pluto at perihelion the Sun has a magnitude of -19.44. That's more than 600 times brighter than the full Moon: still too bright to look at!
At Pluto's aphelion, the Sun's magnitude would be -18.34.

The sun looks like any other star from Pluto.

Roughly minus 3.5 magnitude and about twice the size of Venus at best Viewing. Jules, Australia

Pretty dim...:)
About 1/1400 as bright as it is when seen from Earth.
