Guitars made overseas may require you to enlarge the holes for the larger US spec pots to fit. You will also need to change the metric knobs to inch sized set screw knobs and the switch tip. See related items.

4-way mod requires a separate wire from the neck pickup cover (if it has a cover) for shielding. If you don't have this wire, you can cut the jumper from the cover to the eyelet and solder a separate wire to the cover. 

Some control plates need the switch slot to be slightly elongated for the extra travel on the 4-way switch. This can be done with a small file or metal saw blade.

I Love These Solderless Harnesses

by Matthew -

Install was super easy . I have Essential Tremors and can not solder to save my life. The little bit of work I needed to do to get this harness installed was pretty effortless.
Components are quality and workmanship is way better than I could ever do myself.
I installed on a MIM Thinline Tele that was just ridiculously noisy and it made a huge difference.
This purchase was my 3rd Tele harness. I really appreciate the easy install and the ability to change out pickups when I want to. No extra cost, no wait.
