Solderless Guitar wiring tips
Here are some helpful pointers if you are planning to re-wire your guitar.
- The Solderless series follows a simple colour code to help guide where to put each pickup wire, your ground wires & on certain models, the jack wires. On the solderless connectors you’ll see little colour dots by each lug, the colours are as follows -
Silver Metallic - For the Neck Pickup HOT wire
Blue Metallic - For the Middle Pickup HOT wire
Bronze Metallic - For the Bridge Pickup HOT wire
Green Metallic - Jack HOT wire
Black - For any Ground wire
The Ground wires can be attached to any of the black dotted solderless connector lugs.There is also an additional solderless connector (shown on each wiring diagram as position will vary depending on which harness it is). This is used for any misc ground wire, such as the bridge or vibrato claw depending on the guitar model/specs along with a spare in case your guitar happens to have a ground wire coming from the body cavity shielding paint, which some models do.
- When attaching your pickup wires, you will need to consider the colour code of the wires. Rather unfortunately, no two guitar pickup companies appear to totally agree on a set colour coding to use. Different pickup makers and factories use their own colour codes, so please ensure you refer to their colour code diagrams prior to going ahead with soldering. Depending on the guitar, and type of pickups you are intended to fit, there could be a variety of pickup wire types and colour codes to consider. If you are at all unsure, contact your pickup manufacturer prior to starting the harness install, or failing that, feel free to get in touch with me and I’ll do my best to help! My wiring diagrams have been drawn with either traditional 2 conductor or McNelly Pickups colour codes in mind. Again, a McNelly colour code diagram is available to view on the ‘Wiring Diagrams & helpful technical info’ page of the website.
What types of pickup wires will fit into the connector blocks?
The RS Pro connector blocks will fit ANY pickup wire type, so if you have traditional single coils with cloth covered push-back style individual hot/ground wires, simply push back the cloth covering to expose around 5/6mm of central core wire and insert it into the connector. Tighten up, and push the cloth covering back down.If you have thinner, plastic insulated/coated wires, either simple 2 conductor hot/ground, or 4 conductor Humbucker style wires, they will work with the connector blocks. To prepare those for install, you will need some wire strippers so you can trim back the coating to expose around 5mm of central core wire. Very often these plastic coated wires are stranded wire underneath the coating, so if this is the same for yours, then simply twist the wire so it forms a nice tight portion, then insert that into the relevant connector block and tighten. 4 conductor pickup wires will have a variety of colour codes used by pickup brands/manufacturers, you will need to refer to their information as to which colour wire is hot, ground and series link for example. The series link wires will not be used on a traditional install, so those need to be securely twisted together and taped off.If your pickups are vintage/traditional style 2 conductor 'braided' wire, then these will also fit the connector blocks, you just need to prepare them to do so. First step is to push back some of the outer metal braiding. Then using some needle nose pliers or a small screwdriver, separate some of the braiding so you can twist and form a off-shoot of wire. This will be your ground, so with that twist of wire pop that into the connector block and tighten. Then your central core wire is the 'hot' signal wire and goes into the relevant connector block via the same methods as prior, exposing around 5mm of core to ensure a nice firm seat in the connector. As always, if you have ANY questions or concerns about whether your pickup wires will be suitable, please just drop me a message or call and I'll be happy to help guide. I have tested these connectors with all varieties of pickup wires and they worked great so happily will advise on how to correctly install with you :)

Useful info
I've been proudly making, developing and installing my pre-wired guitar harnesses since the beginning of the Home of Tone back in 2015 (time flies when you're having fun right!). Although I feel I do my best in covering as much information as possible across the various product listings, fitting guides, wiring diagrams and more, I thought it might be helpful to put together this page so I can answer some of the common questions my customers ask either prior to ordering or prior/during installing in your guitar. I'm going to delve into a variety of questions for a range of the harnesses, but I'll try to do so in a clear way to help you find the info you are looking for!
Needless to say, if your question isn't covered here then by all means drop me a message and I'll do my best to help - james@homeoftone.co.uk
Do you make custom harnesses or custom diagrams?
I'm afraid I do not offer a custom harness service, or custom wiring diagram service, in any form.
Only harness kits available are the developed and tested product range listed on the website.
Do I need to take a harness to a tech to install it for me?
This ultimately comes down to whether you own the equipment needed to correctly and safely install the kit, or how comfortable you feel working on your own guitar. I do feel that installing a pre-wired guitar harness is do-able for many guitarists but only if the correct tools are used, that care is taken to ensure you do not damage the kit, your guitar or yourself or have prior experience in the field. There are detailed installation guides here on my website, as well as simple to follow wiring diagrams all to help make the process as easy as possible and in my experience, these have helped thousands of my customers carry out their own install.
However, and importantly, if for any reason you have concerns about fitting the kit yourself, it is best to have a trusted professional tech or luthier fit the kit and help ensure your purchased kit, and your beloved guitar are both looked after and worked on correctly.
I, James' Home of Tone cannot and will not be held liable for any injury or damage caused by incorrect methods, handling and techniques whilst installing a Signature Series pre-wired kit.
If you are local to me (Stourbridge, West Midlands) I take on guitar work no problem at all so will certainly be able to help install your Signature Series harness.
Will I need to modify my guitar to fit a harness?
This ultimately depends on what spec of wiring your guitar already has, or where it is made. My kits predominantly use premium components which are made to imperial specifications by each manufacturer (CTS, CRL, Switchcraft, Pure Tone etc). So if you're planning on fitting one of my wiring kits to your USA made instrument, then chances are the guitar already has imperial spec wiring components/hardware and the kit will be a like-for-like swap resulting in very little or no modifications at all needed to the guitar to fit.
But if you're fitting the kit to an instrument with metric spec components, or it was made in the far east for example, then there is a good chance there will be some level of modification required to fit the upgrade kit. These could include widening the holes in the body or pickguard to accommodate the new pots, needing new control knobs and switch tips to fit the larger pot shaft diameters and switch thread/sizes or using an imperial threaded jack socket/mount. These are all common and normal procedures and changes to make when upgrading a far east, metric spec instrument to premium imperial sized components and within my installation guides and product descriptions will help guide what to expect with this work and in some cases, how to carry out those changes.
If you're not sure what spec of component your guitar has, or where the guitar was originally made, then by all means drop me a message with some details about the guitar and I will certainly help identify this for you, and do my best to explain the level of work required to install it.
Will CTS pots fit my scratchplate/control plate/guitar body?
This is a really important question and one understandably asked a lot. The CTS pots I use across my harness range have a mounting thread diameter of 9.52mm, and a 10mm hole is usually required to mount them comfortably. This is quite a bit larger than common import sized pots seen on Squier, Epiphone or other far east made guitars, which usually have a mounting thread diameter of 6mm or 8mm depending on type or brand used. So chances are, if you have a far east made guitar, you will need to widen the holes in your pickguard or guitar body depending on what type of guitar you have, to suit the larger CTS pots used in a new harness.
To carry out this task, I recommend doing this using a step cutter bit. This is in my experience the safest method as it will reduce the risk of paint chipping around the hole if a guitar body mounted pot, or tear out on a plastic pickguard/control plate.
I usually widen the pot mounting hole on pickguards or bodies, to a 10mm hole to comfortably suit and fit the CTS USA specification 9.52mm shaft diameter. A good technique is to tape off the stop point diameter required on the step cutter to avoid drilling to the wrong diameter hole, and carefully run your drill to ensure an accurately finished hole. Once this is done, you can final finish the hole to straight edges by running a regular 10mm drill bit through for the pots to easily fit through. IMPORTANT- I highly recommend that if you are not comfortable with doing this in any form, or importantly don’t have the correct tools, then please considering taking this to be done by a trusted professional guitar technician. It’s not worth the upset and disappointment in damaging your guitar!
Will my existing control knobs fit the new CTS pots?
Now, this one although might seem otherwise menial, is a really important question as trying to force fit the wrong sized control knobs or even doing so with the correct sized ones in some cases, onto the pot can completely damage them. So please do take the time to read through this one as it could prevent some headaches after everything is installed and a simple control knob ruins your hard work!
I use across my harness range, USA spec pots which for split shaft versions measure 5.95mm with 24 splines, and 6.35mm for solid shaft versions.
In most cases, the original control knobs on import type guitars such as Squier or Epiphone for example, will have metric sized, smaller fitting control knobs suited to smaller pot shaft diameters. These items simply won't fit onto the larger USA spec pots I'm afraid. If your guitar is a Fender or a Gibson, USA made guitar then chances are your original control knobs will fit onto the new harness pots just fine. But it is still VERY important to ensure care is taking when installing those push-fit control knobs as damage can still be done to the pot if fitting incorrectly believe it or not. For each harness I have included the measurements of the pot shaft type used in that particular kit. I hope this helps identify if the pots used in that kit, will suit the control knobs you already have, or whether you need to order new ones to suit.
These details are the same for switch tips too. For example, threaded switch toggles like those used on Gibson style guitars for example will have a specific thread pitch/size. As I use Switchcraft USA toggles (imperial thread) and CRL/Oak switches these will both require USA/imperial spec tips, much like with the control knobs.
