Any intro to soldering or guitar wiring video/guide will help if you're new to soldering.

Here's the Pitbull Intro to Soldering video, and 'How To' thread with related video links. And, Doc's Mini soldering tutorial for step by step through the process.

Take your time, work out where things need to go/reach, prep your wire lengths and surfaces, don't over-heat parts, ask if you need help.
