If you are migrating to a standalone ECU (like a Haltech, Link, or MaxxECU), you can completely eliminate the complex factory automatic transmission wiring, immobilizer lines, and emissions controls. You only need to patch into the crankshaft, camshaft, coils, injectors, throttle, and fluid temp sensors. Regardless of the year, the 2UZ-FE ECU relies

He documented the pinout in a tidy PDF and saved it to his toolbox laptop: a clear legend, voltages, expected idle waveforms, and common failure modes for each pin. A few weeks later, a friend called with the same symptoms. Jake emailed the pinout and walked him through the test steps over the phone; the repair was the same—corroded connector on the crank sensor circuit. The friend’s gratitude was terse and relieved: “You just saved me a tow and a week of guessing.” Have a specific pin you are stuck on
