I’m building a fairly complex 4 control modded harness. And I thought, maybe some of the guys out there don’t know about this subject (though, probably many do). Anywho, I thought I’d share about the benefits of using Silicone Wire in guitar harnesses.
Sometimes, Pushback cloth wire can become cumbersome in a complex harness, especially if one is dealing with a back cavity. One needs something with ultimate flexibility. Enter silicon wire. Silicone wire is just the bees knees🐝. It is extremely inexpensive, comes in a variety of colors, extremely flexible, easy to thread small dpdt lugs, and you can hold the soldering iron on it and it will not burn!! I know a lot of guys use regular PVC wire; but, if you’re ready to modify or build a new harness, consider silicone.
I use 22 and 24AWG, it comes in many colors and is cheap if you look around a bit.
Now you don’t need all these colors. Red and Black do fine. And if you look on EBay, you can find 45ft of Red, Black and Blue in a lot (22 AWG) for $7.59!! Enough to do your guitar and extra for your workshop.
No fighting with rigid pvc that even the best solderer can scorch, silicone wire lasts a millennia. Your wiring will go forward in perpetuity with no rot. Ha!!
And if one is wiring rotary switches, silicone wire makes your life so much easier.
Here's one I put in the oven earlier(!) It's a three way eight pole for selecting 8-pin DIN sockets to allow multiple connections to a single outlet and the Eddystone box is about four inches long. I couldn't visualise using anything other than silicone insulated flex for that, especially with all the tiny bits of polyolefin over the tag contacts.
It was a labour of love just ringing it out afterwards!
