Trail Grid Pro Speaker Wiring Harness Adapter Kit — 2016–2023 Toyota Tacoma
Swapping speakers in a third-gen Tacoma should not mean cutting into the factory harness. These Trail Grid Pro adapters plug into the stock speaker connectors on one end and your new speakers on the other, leaving every factory wire intact.
They are the same harnesses Trail Grid Pro builds into its Alpine and Kicker Tacoma speaker kits. Pick the JBL amplified or non-amplified set to match your truck: a JBL logo on the door speakers means JBL amplified.
| Spec | Detail |
|---|---|
| Fitment | 2016–2023 Toyota Tacoma, all trims |
| JBL amplified positions | 2 dash, 2 front door, 2 rear door |
| Non-amplified positions | 2 dash, 2 front door, 2 rear door |
| Connection | Plug-and-play to factory connectors |
| How to tell if you have JBL | JBL logo on the door speakers |
How do I know if my Tacoma has the JBL system?
Check the door speakers. If they carry a JBL logo, the truck has the JBL amplified system. No logo means it is non-amplified.
Will I need to cut or splice wires?
No. The adapters plug into the factory speaker connectors and can be removed later to return to stock.
Which speakers do these adapters cover?
Both versions cover two dash, two front door and two rear door speaker positions.
Does this kit include speakers?
No. It is the harness adapter kit only, so you can pair it with the speakers you prefer.
