We highly recommend checking out the Home of Tone or McNelly Pickups Wiring Diagrams when fitting your new McNelly Pickups, or perhaps re-wiring your guitar or fitting one of our pre-wired harnesses. They're tried and tested by both McNelly and Home of Tone and might help you get creative with the workings of your guitar!. Here are view-able PDF documents showing clear wiring diagrams for a range of common configurations.

Install Guides
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 more than up to the job of helping you fit your harness. I do personally recommend a 40w iron, this will provide ample working temperature for guitar electronic components. I use a temperature variable 40w iron and it works great for this application. For commercial product reasons, I have to use lead free solder. I personally use Rapid brand lead free, as the silver mix helps the solder flow much better. It’s available in small lengths too.

- When soldering your pickup wires, you will need to consider the colour code of the wires. Different pickup makers and factories use their own colour codes, so ensure you refer to their colour code diagrams prior to going ahead with soldering. My wiring diagrams have been drawn with McNelly Pickups colour codes in mind.

I do understand for some rewiring a guitar can be a daunting task, but it can be a rewarding job to carry out if done so with the correct knowledge and tools. But 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.
