Trail Grid Pro FAQs
Who is Trail Grid Pro?
Trail Grid Pro is a Toyota-focused parts and bundle company in Frederick, Maryland. Cliff John started it in 2021 with plug-and-play audio upgrades.
What warranty does Trail Grid Pro offer?
Most products carry a one- or three-year limited warranty depending on the item, and manufacturer terms apply where specified. Cut or modified wiring and physical damage are not covered.
Why does my Trail Grid Pro item show a lead time?
Most bundles are assembled after you order, and the lead time on the product page covers that assembly. Faster shipping does not shorten it.
How do I know if my Toyota has JBL?
On a 4Runner, check for an 8-inch subwoofer on the passenger side of the cargo area. On a Tacoma or Tundra, look for JBL badges on the door speakers or an amplifier under a front seat.
Are the audio kits plug-and-play?
Yes. The bundles are built around plug-in harness adapters, so factory wiring is not cut. Make all connections before powering the system on.
Will a '16–'23 Tacoma harness fit a 2024 Tacoma?
No. Harnesses and brackets are sold by generation, so match the part to your truck's year range.
