    Good morning all.
    We are new to the world of the Lexus and have a 3uz from a GS430 we are stripping which we are going to fit into our Land Rover 110 Defender.
    I have been told the wiring is fairly simple, apparently only needing 6 wires, but I am wary of this fact as i doubt it can be that easy. Is there a decent wiring diagram for the GS430 or 3uz engine ??
    Thanks in aďvance.
    Paul.

    Once I've finished they only take a few wires to make them run as long as you don't count the many wires I connect to get to that point.

    Over the years I have purchased all of my diagrams and then added to them with my own hand written scribbles to make up good instructions for wiring all the 1uz engines. I'm yet to compile all my 3uz info into something that's understandable as it's a bit more than the 6 wires you speak off , especially when doing Auto.

    Soon I will have then available.

    I should have instructions ready for sale in a week or so. I've got another one to wire on an aftermarket ECU first.
