1) Swap the Supra 3 pin plug to the new Tundra 4 pin plug. PN#90980-11964. Supra 3 pin to 4 pin, respectively goes like this: (yellow/green stripe) 1-->4, 2-->2, (beige)3-->1, plug up the third pin with an OEM plug or RTV silicone. 2) The Tundra alternator uses a metric 6mm for the power cable instead of an 8mm like the Supra. 3) Yes, you can directly swap over your Supra pulley (in case you have a pretty one you paid good money for). 4) When you mock up the alternator on the lower bolt, then rotate the alternator so the top ear hits where it's supposed to mount, you can use a marker to trace where it hits and then unmount the unit. The mask off the sides and take it to a machine shop to be machined down (5mm of material as shown.) On the top ear in the first picture, note the small black mark I made... In the second image, I masked around the portion of the lip that will be shaved. Notes: The alternator is smaller, and subjectively feels lighter (I'll weigh them tomorrow.) The third ear on the Tundra unit doesn't get in the way and isn't used. Remove the 10mm bolt holding the harness support as it won't be used. Enjoy alternator superiority! I'll have mine back from the machine shop tomorrow, but no update means I'm happy with it. 2003 to 2008 4.7L V8 2UZ-FE.
