About this lighting

The In.Ye Light Harness 9920-400489 is a genuine Gecko Alliance OEM replacement wiring harness designed for MSPA and In.Ye spa lighting systems. This 8-foot cable assembly features a 3-pin JST connector plug that provides reliable power and signal transmission to your spa's LED lighting components, ensuring proper illumination and color-changing functionality in your hot tub.

Built to Gecko's exacting specifications, this light harness delivers the exact fit you need for seamless integration with your spa's control system. At Bubbles Supply, we guarantee this OEM part will match your original equipment perfectly, and we'll ship it the same day you order.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Spa lights completely dead with no response
  • Lights flicker intermittently or cut out under load
  • Color-changing function stops working while other lighting still partially functions
  • Lighting circuit throws a fault code on the control panel
  • Visible damage, melting, or corrosion on the existing light harness connector

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your spa uses a Gecko In.Ye or MSPA control system — this harness is not universal
  • Locate your existing harness and verify it uses a 3-pin JST connector before ordering
  • Check the cable routing path to confirm 8 feet of length is sufficient for your cabinet layout
  • Inspect the control pack board for burn marks or corrosion — a damaged board may also need replacement
  • Note the connector orientation on your existing harness before disconnecting, or photograph it first

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
