How can I (by myself) change the bridge pickup from a strat (single coil)?

Now I mean step-by-step directions, and if it's any help, the pickup that will be going in is a Seymour Duncan SHR-1 Hot Rail.

Just remove the pickup that you wish to replace and solder the new one right back in its place. There are only two wires. Super easy!
to connect the wires you need a soldering iron or something like that. to remove the pickup a screwdriver and then something to disconnect the wires ( i dont know whaT)
