Wiring diagrams & helpful technical info
First of all, I want to say a heartfelt thank you for choosing one of my pre-wired harnesses for your guitar. Whether it’s for a long overdue repair, upgrade, modification or a project, I honestly enjoy making them for you all and the response from guitarists since introducing them back in 2015 has helped that enjoyment grow further, so thank you for the continued support.
Here you will find the wiring harness fitting guide, and list of wiring diagrams to assist you in installing your Home of Tone wiring harness. Do please take the time to read through the fitting/install guide. I have written it to help you with your install, to help the process be as stress free as possible, and to hopefully cover any questions along the way!
Please take care of yourself and your guitar when carrying out any guitar wiring work and I cannot be held responsible for any damage caused by in-experience or incorrect techniques used.

These wiring diagrams are for personal use, not to be sold(!) etc. I list them here to help my customers when fitting their new pre-wired harnesses but I hope they may be of some help to more of you too. Please take care of yourself and your guitar when carrying out any guitar wiring work and I cannot be held responsible for any damage caused by in-experience or incorrect techniques used.
I am currently working through writing install guides for as many guitar types as I can. It'll be a continued project, but for now, here are the guides I have written. They may help when installing your new wiring harness.

Guitar wiring tips
Here are some helpful pointers if you are planning to re-wire your guitar.
- Most hobbyist soldering irons we have in our tool cupboards at home are up to the job of helping you fit your harness. For working on guitar electronics, I personally recommend a minimum of a 40w iron, this should provide ample working temperature for the task at hand. A variable temperature iron can prove to be useful for guitar wiring too, as soldering lugs doesn’t usually require as high working temperature as soldering grounds on pot casings for example. Again, this is something that practicing solder techniques on old components can prove useful to get a feel for operating temperatures suitable for each task to ensure a solid solder connection is made and no damage is caused to any component or your guitar.
- Due to commercial product reasons, I have to use lead free solder to complete my wiring harnesses, so if you plan to use the same during your install, I personally use and recommend Rapid brand 22SWG 0.7mm lead free solder.
- When soldering 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.
- Although a complete, pre-wired harness can offer a guitarist the simplest solution to swapping your guitar’s wiring, we do recommend taking your time to familiarise yourself with the task ahead before attempting to fit. I do understand for some new to guitar wiring that it can be a daunting task, but it can be a rewarding job to carry out if done so with the correct knowledge, tools and preparation and something I feel is skill that is of great benefit for all guitarists to learn. Soldering is a somewhat simple task, but good technique is achieved from practice and you’ll need to ask yourself whether you’re keen on practicing that technique on your pride and joy guitar. I honestly don’t want to deter anyone inexperienced in guitar wiring from giving it a go, but perhaps find some old or broken pots for example and practice getting used to feeling the solder flow and when it ‘takes’ to a surface, this could be a big help when it comes to installing the harness and reduce the risk of damaging your new harness or guitar. With that being said, if you are at all unsure about fitting, I do highly recommend getting a professional and importantly, trusted guitar technician to fit the harness for you. If you are local to my office (West Midlands based), I do also offer a fitting service of my harnesses if required or if you’re not local, I have began to compile a small list of trusted techs I would be happy to recommend across the country.
