This is taken from some old guides I wrote on another forum.

It seems that a lot of people ask the same questions about this stuff. Rather than explain it every time, refer them here. This is aimed at the beginner to moderately educated guitar player. Seasoned pro's and players who have done it all (setups, rebuilding, ryv) won't get anything from it, though, you are more than welcome to comment.

So, you decided to change those old pip's? Firstly, wire colors and non-OEM wiring are beyond the scope of this thread post. To get into those areas I suggest these links.

Soldering for Dummies:
First you must have some basic equipment. I'll quote Radio Shack part numbers because they are common stores. You don't have to buy from here and better deals can be found. A good soldering gun would be a 30 watt "pencil ", Radio Shack number 64-2067 for $7.69. Any higher wattage is unnecessary and could possibly damage the components / wire if heated to long. Stay away from the 100 watt "guns", with the hooked tip. This is overkill for a beginner and hard to use in small spaces. A good solder would be a rosin mixture ("rosin" is used to help the bonding process of metal to metal), RS # 64-013 $3.99 and is in roll form . This should last anyone a while. The most important piece is a multimeter. A small device with an analog meter/needle (or digital if you prefer to spend more) with two leads. Cheap ones measure DCv,ACv, Ohmic resistance / continuity and sometimes Amps ( RS # 22-218) ..Measuring ohm's is important for guitarists. Finding shorts or unconnected leads helps to solve many problems. To check for a short, measure two points of a circuit ( a wire for example, both ends) if the meter goes to zero(no resistance), it is short or open (on the wire, this would be normal to measured this since the wire is one piece, if it didn't then there is a break in the wire somewhere). Volts, amps and ohms can be confusing at first.

To simplify, think of this water analogy.

Voltage :water pressure
Ac :water moving back and forth
Dc : water flowing in one direction
Amps :amount of water
Watts : force/work of water
Ohms : resistance of moving water

This is just to simplify for someone new at this. It's a little more complex than this, but enough to get one going.

Installing the pup's: How to solder

Know what you are going to connect (have a plan of what needs to be done) before the old pip is taken out. Every guitar is different and every pip manufacturer uses different colors to determine what goes where. Use the above links if you having trouble.

Let the gun heat up. Have a wet sponge in a small dish. Before you apply solder, wipe the hot tip a little. This cleans it and gets rid of any impurities that might affect your connection. Don't bother wiping / cleaning the tip after you've made the connection, it will just dry up. Leave it till your ready for the start of the next connection. Don't worry if the tip rusts quickly, heat accelerates the oxidizing process. After you wipe the tip, apply and melt a little solder to the tip. This will aid in the heat transfer to the wire to be connected. (Just a small dab.)
On your connection to be made, leave at least a 1/4 inch wire exposed, twisted if possible - this keeps wire from splitting out all over as you work with it.

HEAT THE WIRE AND OR CONNECTION, NOT THE SOLDER ITSELF!

This is the #1 rule for a good connection. Have the tip on the bottom and the fresh solder on top. Let the newly heated wire melt the solder and it will flow onto the connection. Melted solder will always flow to the hottest point so try to make the wire the hottest point. It will try to get to the tip of the soldering iron. THIS IS NOT WHAT YOU WANT! Allow it to cool by itself, don't blow on it as this causes a poorly connected joint. Use a stand to hold the Soldering Iron, and be careful not to burn yourself, it's easy to do in the small guitar cavities.

A few secrets:

If you're a vintage/OEM freak and want everything perfect, then don't bother with what follows here. For someone who changes pip's a lot, wants to try out a lot of different pickups quickly or wants an easier time with their "junker" guitar. Here are some shortcuts:

A lot of time you will find that there is a lot a junk all soldered at one point. When installing a new pip, all this stuff comes loose and has to be reconnected. You don't have to use all of the new wire on the new pickup. You can splice it in the middle or near the old pickup wire pickup itself. For someone who changes pickups a lot this is good. This connection can be used over and over, just remember to wrap the bare wire in some black tape to prevent any shorts. The sound quality loss is minimal if a good connection is made.

If you just bought a new pickup and you are really not sure if it's going to work for your sound, add a little bit of wire and use some auick connects (solderless connectors). You can compare pips very fast by changing them. Once you settle on a plan, you can go in, remove the wire extension, and solder them in. Sound quality loss will be minimal if a good connection is made, but I wouldn't leave it like this unless you change sound a lot.

One thing to remember, and this is crucial. Do not buy ACID CORE solder. This type is used for plumbing. Most k-mart or hardware type stores put each type right next to each other, so it's easy for a newb to make that mistake.
Also, after you solder a connection, you may seem some brownish residue ( espicially on the back of the pots ). This is called "flux" and is perfectly normal. There is no need to use Flux remover on these type of connections.

Solder iron 64-2067 is no longer offered by Radio Shack would this kit be a better alternative?

also flux is for plumbing, you don't need it for electronics.

Not true , flux is used in electronics in some instances.

From wiki, cause I'm too lazy:
Solder often comes pre-mixed with, or is used with, flux, a reducing agent designed to help remove impurities (specifically oxidised metals) from the points of contact to improve the electrical connection. For convenience, solder is often manufactured as a hollow tube and filled with flux. Most cold solder is soft enough to be rolled and packaged as a coil making for a convenient and compact solder/flux package. The two principal types of flux are acid flux, used for metal mending, and rosin flux, used in electronics, where the corrosiveness of the vapours that arise when acid flux is heated could damage components. Due to concerns over atmospheric pollution and hazardous waste disposal, the electronics industry has been gradually shifting from rosin flux to water-soluble flux, which can be removed with deionised water and detergent, instead of hydrocarbon solvents.

I didn't think anybody read these guides I wrote. I wrote these way back before ss.org existed, when I was slumming around on HC..

[JPMDan]

so what about the solder iron I found? Also would you like me to search for new part numbers to update your post? I'm a do it yourself kind of guy and rather solder my own shit

[D-EJ915]

Really any soldering iron that's at least somewhat powerful 20 watts or more will do you just fine, get a feel for how it works and you'll be fine. I know guys use 100 watt irons but they're so used to it they'll never damage a component.

One thing I would like to add on the soldering front. The choice of solder should be a subject of some consideration. In many cases you will want to use some manner of flux to help the heat spread well, and you may be using some heat sinks to help keep the wrong parts from getting too hot and possibly damaging plastics (such as insulation).

Having soldered several dozen circuit boards in the last few years, you need to keep in mind the fact that you will have to wash whatever you solder after it cools to remove the excess flux and the impurities that come out as you cook the connections. Failing to do so will leave nasty chemicals in your circuit that can oxidize and change the electrical nature of the connection, or corrode some parts.

The solder spool will say how to clean up, but my recommendation would be to use an organic core solder, such as Kester "Red Box" organic core solder. The benefit of this is you don't have to use alcohol to clean up (which can do nasty things to paint finishes on guitars) but uses water instead. You can usually get this from places like Mouser.
