Improved USA connectors that won't crumble with age.

SuperGY6 connectors and fuse holders are all 3D printed right here in the USA. Even the raw plastic material is made and sourced in America!

This is because original nylon connectors tend to crumble and fall apart after a season or two of sun exposure.

The type of plastic used is Polyethylene Terephthalate Glycol (PETG) plastics for strong UV resistance.  PETG is approximately as strong as nylon brand new, but keeps that strength over time despite frequent sun exposure.  

All connections clearly labeled!

Every connector on the harness is labeled and tells you exactly where it goes. Absolutely no guesswork or head scratching. Super simple install!

Available upgrades

These plug-n-play upgrades can be bundled at a discount now, or installed easily later.

These upgrades are modular, and install on top of the base harness without modifying it.
No rewiring, soldering, or splicing is ever required.

    High demand periods 🕧
    I occasionally get a rush of orders all at once and it may take up to 3 days to build and ship your order. These "high demand" periods are usually around holidays, spring time (as things warm up across the country), and in July around the 4th. So please plan ahead when ordering around these times, don't wait until the last minute!
