The PHR Tundra/Sequoia Alternator Adapter Harness allows you to adapt your existing alternator harness to a larger 2UZ alternator.
The OEM 2JZ alternator delivers between 90 and 105 amps.
The 2000-2006 Tundra utilizes a 130 amp alternator.
The 2000-2007 Sequoia utilizes a 150 amp alternator.
Please Note: slight modification of the 2UZ alternator housing will be required to fit the 2UZ alternator to the 2JZ engine. There are several write ups on how to do this available online.
