IS300 Wiring Diagrams

Attached are both the wiring diagrams for the 2001 and also 2002-2005 Lexus IS300.

Disclaimer – I don’t take any responsibility for these diagrams, these do seem to be the factory wiring diagrams but I always like to double check / cross reference any wiring. Also I do not own a IS300 and can’t confirm these diagrams.

IS300 2JZGTE VVTi Swap Manual

After reponding to a question on here I figured it made sense to host a link of this IS300 2JZGTE VVTi swap manual. Although I didn’t do the swap personally or own an IS300 I think it’s a great swap write up that applies to most late model 2JZGTE VVTi swaps and engine swaps in general.

The document also contains information I have provided over the years on supraforums and has pictures I have provided.

A big thanks to Indirocz28 from http://my.is/forums/.

As a side note please don’t reference the pinouts in the manual, if the author ever updates the word document with my new pinouts I will re-upload.

***UPDATE – IS300 ECU pinouts can be found here – http://www.2jzgarage.com/2013/04/lexus-is300-ecu-pinouts/ and IS300 Wiring Diagrams can be found here – http://www.2jzgarage.com/2013/04/is300-wiring-diagrams/

Toyota Supra SZR to RZ conversion (2JZGE – 2JZGTE VVTi)

The last video I’m uploading tonight – the video that started it all for me to get into this supra media coverage/publishing. Now over 120,000+ views on youtube I’m pretty stoked and overwhelmed by the reponse. Although a simple video diary of pictures and seems to hit the spot with viewers. At the time I had no idea about cars or supras but managed to do the conversion successfully with the help of guys from supraforums and friends/family.
