If you are putting a 2UZ-FE into a different chassis (like a Hilux, older Land Cruiser, or drift car), keep these integration factors in mind:
The 2UZ-FE is Toyota’s legendary 4.7-liter V8 engine. It powers iconic vehicles like the Land Cruiser, Sequoia, Tundra, and Lexus LX470. Because of its iron-block durability, it is a highly popular engine for custom swaps into older trucks, drift cars, and off-road rigs.
Total pins: 68. Some hybrid models (like the 4Runner) use a 4th smaller connector for chassis integration.
Switched 12V power inputs coming from the EFI Main Relay.
Ignition switch signal that tells the ECU to wake up when the key is turned to "ON."
: Non-VVTi (mostly). These often use a 5-plug ECU configuration. 2005–2009 Tundra/Sequoia/GX470
He reached for the ECU connector kit and unclipped the dusty cover on the firewall-mounted ECU. The plastic housing looked unremarkable, but to Jake it was a map: dozens of pins, each one a promise of what he needed to know. He needed the pinout—precise, reliable—so he could back-probe without tearing apart looms or guessing at signals.
Before chasing sensor codes, always verify the engine computer is getting power. The standard operating voltages are as follows:
The Toyota 2UZ-FE V8 engine is a legendary powerplant, known for its million-mile durability in the Land Cruiser, Sequoia, and Tundra. However, when it comes to engine swaps or troubleshooting electrical gremlins, the ECU (Engine Control Unit) wiring is often the biggest hurdle. Because this engine spanned over a decade, the pinouts changed significantly with the introduction of VVT-i and Drive-by-Wire systems.
"Universal pinout" posters on eBay. The 2UZ changed too much over its 13-year run.
I'll open these pages to extract ECU pinout details, connector types, and other relevant information. search results show some information, but detailed pinout tables or diagrams are not directly accessible. The jdmfsm.info page might contain a table, but it's not fully captured. The drive2.ru page might have some information but is in Russian. The efiautos.com page seems to be a placeholder. The toyotanation.com page mentions ECU flashing differences. The v-tuning.eu page might provide some details. I need to search for more specific pinout information, possibly in PDF format. I'll also search for "2UZ-FE ECU pinout PDF" and "2UZ-FE ECU pinout diagram PDF". search results show some potential sources. I'll open:
Bookmark this guide, print the official diagram for your specific year, and take your time. Wiring the 2UZ correctly the first time is infinitely easier than chasing a blown 20-amp EFI fuse on the side of the road.

: Typically uses a 4-plug or 5-plug aluminum housing interface.
Beyond the basics, several specialized systems interface with the ECU:
