Plug-'n'-play Haltech engine management for Toyota offroad builds. Every kit here pairs a Haltech ECU or VCU with a vehicle-specific adapter harness, so the swap is a connector change rather than a rewire.

Coverage includes the Tacoma across 2RZ-FE, 3RZ-FE, 5VZ-FE, 1GR-FE and 2TR-FE, the 4Runner in 3RZ-FE and 5VZ-FE, and the 80 Series Land Cruiser 1FZ-FE, with Nexus R3, R5, S2, S3, T1 and T2 units alongside Elite 750, 2000 and 2500 options. As a Platinum Haltech dealer we can match the right controller to your engine, wiring plan, and trail or race goals, then remote tune it once it is in the truck.
