How to replace your guitar pickups

Guitarists sometimes replace their stock pickups in the hope of improving their guitar's tone. This step by step guide shows you how to swap your existing guitar-pickups for new ones. 
The instructable is written by John Smith who changed the bridge pickup on his Squier Telecaster  to a Seymour Duncan Little '59 in the hope of a more Les Paul type of sound. But the same technique should be equally useful for other guitars.
The problem I found with swapping pickups is that it's difficult to objectively compare the tone before-and-after, especially if you change your strings at the same time.
