Demystifying Humbucker Color Codes

Have you ever tried following a wiring diagram and instantly became confused by the colored wires on humbuckers? Have you ever been confused looking at humbucker color codes online? Are you looking at different colors than what your humbucker currently has? Have you followed the installation perfectly but got a different result than you expected?

If any of the above situations sound familiar to you, we can help. The solution is straightforward, but instead of simply giving you the answer (we intend to do just that later), let’s also learn a bit about humbuckers while we’re at it! So, without further ado, let’s start by demystifying humbucker color codes.

Color Me…Different?

Let’s get this out of the way: there is no industry standard regarding humbucker color codes. Each manufacturer has a coding system that works best for them – and that’s cool! Except, there are a million different wiring diagrams out there, each from other manufacturers – so confusion will undoubtedly happen.

Humbucker Wiring Basics:

We hope to dispel this confusion in this article by showing you the basics of humbucker construction and wiring. Let’s first take a quick step back and give a refresher on how we wire humbuckers up:

Basic Humbucker Construction & Wiring

A standard humbucker features a Screw coil (indicated by the screw pole pieces) and the Slug coil. In order for a humbucker to work, these coils need to be wired in series. In the example above, we are indicating the series connection with the Green and Red lead. This connection is usually soldered together close to the pickup and carefully taped off.

Some manufacturers use the terms “North” and “South” instead of Screw and Slug. In this case, Slug Coils are “North” and Screw Coils are “South”.

These wires actually have names! Since each coil has a “Start” and a “Finish” we use terms like “Inside Screw” and “Outside Slug” to indicate the different leads. In our terms, the “Inside” is the Start, and the “Outside” is the finish – the last wire turn of the coil. See below for an example:

Don’t glaze over just yet! Stick with us, as understanding this concept will make everything easier.

You’ll see us use “with shield” a lot in this article, but won’t see any illustrations of the shield. Just note that the shield always connects to ground.

Gibson Braided Lead

Before we get into humbucker color codes, it’s helpful to understand how a humbucker is wired using Gibson braided lead. Gibson Braided lead is, fortunately, an industry standard. It is a single-conductor lead, meaning there is only one “hot” signal. The metal braiding around the lead should connect to ground. See below for an example of how we wire this up:

Fralin Gibson Braided Lead Example

In the Gibson Braided Lead example, we use the Inside Screw as our Hot, and the Inside Slug as our Ground. The series link connects at the pickup, is wrapped in tape, and tucked neatly under a cover, or protective tape. If you’ve used our Pure P.A.F. or Modern P.A.F. before, you might have used this lead.

2-Conductor With Shield

While Gibson Braided lead has its strengths as an easy lead to install and work with, it certainly has drawbacks. For one, you cannot reverse the pickup phase or coil direction with Gibson Braided lead. This can leave you in a tricky spot if you ever plan on mixing two different manufacturers’ humbuckers together. If they are out of phase, you cannot simply reverse the polarity of one to fix the issue. More on that topic here. That’s where 2-Conductor with shield comes in.

This lead is very similar to Gibson Braided Shield, except White & Black are reversible, allowing you to reverse the phase. Again, the series link connects together at the pickup, similar to Gibson Lead.

3-Conductor Lead – Humbucker Color Codes

Okay, so…phase reversing is cool and all, but what about coil splitting? Well, that’s where 3-Conductor Lead comes in! See below how we hook this lead to a humbucker. It’s important to note that our 3-conductor lead has a White (hot), Black (ground), and a Red (coil split). If you’re not sure how coil-splitting works, check out our in-depth guide here!

In this lead, the series link gets soldered at the pickup, but travels the length of the lead, allowing you to coil split the Humbucker. When not in use, simply use some masking tape on the Coil Split (Red) Lead to make sure the series link doesn’t short out on anything.

4-Conductor With Shield – Humbucker Color Codes

Now that you’ve made it this far, 4-Conductor should be easy to understand:

4-Conductor lead gives you infinite control over how your humbuckers are wired. Meaning, you can actually re-wire the humbucker without cutting into the tape and changing the way the humbucker is wired at the actual pickup.

Also, 4-Conductor gives you the ability to perform the Series-Parallel Modification. If you need to use this lead, make sure that the series link still connects together – or else, your humbucker will not work.

How To Match Humbucker Leads From Different Manufacturers

Whew. Hopefully, that wasn’t too difficult to understand. In essence, every Humbucker has a minimum of 4 Leads, and the different lead choices give the user as much control over that wiring as they desire. Now that we have a firm understanding of how humbucker leads are wired, let’s get into how to match them up.

See below for some examples of color matching different manufacturers humbucker color codes:

Seymour Duncan® Example

In this Seymour Duncan example, the color codes are widely different.

In the above example, Seymour Duncan’s Black is our White. The color codes are widely different, but learning how to match the humbucker color codes assures us that everything will work correctly.

What if you had a 3-Conductor Lead? Well, it’s simple! See below:

Gibson® Example:

In this Gibson® example, their Red is our White.

As you can see, it’s not difficult to match these humbucker color codes together, but it does require a bit of research to see what codes are what. Bookmark this guide and the following guides below!
