About this union/fitting

The Gecko Alliance Light Harness Adapter 9920-401507 is a specialized 3-position connector that bridges in.ye and MTA connections in Gecko control systems. This OEM adapter ensures proper electrical continuity between your spa's lighting components and the main control pack, maintaining safe and reliable operation across compatible Gecko-equipped hot tubs and swim spas.

Engineered to Gecko's exact specifications, this genuine replacement part delivers the precise fit and performance your spa system demands. We guarantee an exact fit with same-day shipping on in-stock orders, backed by our comprehensive 1-year warranty for complete peace of mind. When installing, ensure power is completely disconnected and verify proper connector orientation before making connections to prevent damage to sensitive control components.

Common symptoms this part fixes

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

  • Spa lights completely non-functional after control pack service
  • Light connector won't seat properly at the control pack
  • Intermittent lighting caused by connector mismatch
  • Lighting circuit throws a fault on in.ye-based Gecko systems
  • Lights flicker or drop out under load

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

Before you buy — quick checklist

  • Confirm your Gecko control pack uses in.ye or MTA light connectors — check the board label or existing harness ends
  • Verify this adapter matches the connector gender and pin count on your existing harness
  • This is an OEM adapter, not a universal fit — cross-reference your control pack part number before ordering
  • Inspect the existing harness for damage; a failed adapter may indicate a wiring issue that also needs attention
  • Confirm the lighting component (LED assembly, light module) is intact before replacing the adapter

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