Delboy52 Posted October 5, 2013 Share Posted October 5, 2013 Been trying to find these diagrams with little luck. The ECU I have was in a year that the V8 recieved a revision change and most of the manuals refer to the old engine. Does anyone know where I can find these diagrams or better still have access to them? Has to be the 1997. I'm trying to find out of this manual covers the VVTi. http://www.faxonautoliterature.com/1997-Lexus-LS-400-Wiring-Diagram-Manual-Original-P18896.aspx I want to be sure before importing and am waiting on a retailer to confirm.

straightsix Posted October 11, 2013 Share Posted October 11, 2013 Have you tried Lexus themselves? They will usually print out wiring diagrams if you ask nicely (and pay!) I have imported manuals from Faxon - they're quick, reliable and well priced. I've got most 1UZ wiring diagrams but not for the 1997 VVTi. Make sure you can get around the immobiliser before fitting.

Delboy52 Posted October 11, 2013 Author Share Posted October 11, 2013 I did try Lexus but they didn't have the diagrams in the system. Or possibly too lazy to check for the paper ones.. Ordered a 97 wiring manual from faxon also. Taking a chance if it will cover a vvti. We have the 98 diagrams and are going by them for now. The ecu is already back from nz to bypass the immobiliser.

Hmm, call a different dealer, I'm sure they have them and are just being lazy...I can't stand when dealers do that! Quote Link to comment Share on other sites More sharing options...

Delboy52 Posted October 15, 2013 Author Share Posted October 15, 2013 Yet to find out Scott if this manual covers my ECU. Annoying that mine is in a cross over year and most of the documentation covers the previous engine revision. If we are still stuck and can't use the 98 diagrams I'll hassle some more Lexus dealers Quote Link to comment Share on other sites More sharing options...
straightsix Posted October 15, 2013 Share Posted October 15, 2013 You might get somewhere on Lextreme - somebody may have some info they're prepared to share - - - Updated - - - Also - have you joined the 1UZFE group on facebook? There's quite a few on there that may help Quote Link to comment Share on other sites More sharing options...
Delboy52 Posted October 15, 2013 Author Share Posted October 15, 2013 Had a look around v-eight.com and lextreme but couldn't find. No doubt the info is probably buried somewhere there.. Didn't know there was such a group on FB. Requested to join, cheers. Quote Link to comment Share on other sites More sharing options...
straightsix Posted October 15, 2013 Share Posted October 15, 2013 Try posting on one of those sites for info. There's a lot of people in Aus and NZ that have used VVTi engines in their conversions. Quote Link to comment Share on other sites More sharing options...
