    Damn Foxo, Rapidshare have withdrawn there free "standard" offering as of 1-7-14, can you believe? I'll have to do something different. In the meantime, I can email,mail all the details to you if you don't mind giving your address??

    Cheers, Jamie

      Hi Dan,
      Is yours the V6 4lt? If so from 8/2004 it has a different PCM (ECU for trans). It has 5 plugs instead of 4. The wiring is different also. The wires you will be looking for are Green/red (trace) which is 12v positive. And Yellow/red (trace) which is earth switched. It is this wire that will do the lock up, but through earth. They will be in the second plug from the top or bottom.Mine is fed 12v power to lock up, this would be earthed to lock up.
      NOW if it is up to 7-2004 it shows it doesn't have a lock up convertor. Which is a bit puzzling?? If someone has more info on this, please report.
      Let me know how you get on Dan?
      Cheers, Jamie

        Ah jeez now I'm bloody confused! I have a 2003 1KZ diesel. I have 4 plugs. It must have a lock up because the bloody AT overheats at all the right times. From the look of your photo's you have wired into the 2nd plug but your wording says 3rd plug? I split the pink wire/white trace from 2nd plug and when I hit it with 12v I can hear a solenoid activate which is promising. When I drive it feels no different, even just 12v in and coming to a stop after getting out of first gear the car still idles and doesn't stall which tells me it isn't working properly.

        My 3rd plug has no pin/white wire. AAahhh, quite frustrating...

        Let me know if you have any further advice?

        Cheers
        Dan.

          Just having a look through my book again Dan (to refresh the memory!!) . Your vehicle should be exactly the same as mine. Looking at my photo of that plug (and going by my memory) it is the 3rd plug down from the top and its the PINK/BLUE trace wire. The PINK/WHITE wire you describe in the second plug I cannot find what that does?? But it isn't the lock up..
          Have another look at that 3rd (from the top) plug, PINK/BLUE wire. Has to be there?? It was a bit hard to see. Unplug it and move it around.
          Sounds like you've got the rest sussed though.
          Cheers, Jamie

            G'day again Jamie. Sorry about the confusion with wires - yes I meant the Pink/blue wire. However, checking again tonight, there is a pink/blue wire in the 1st, 2nd and 4th plug. The 3rd plug is the only one without the pink/blue!! bloody heck. So I tried the 4th plug pink/blue wire and this time applying 12v I hear another solenoid moving however this time it's much quieter. I think the other solenoid may have been the starter motor judging by its sound. So test drive and I think I can feel something different when applying power, sounds like it just applies power straight without spinning up like usual but might just be a placebo playing with my head. I stopped with the switch engaged but the car didn't stall and I'm thinking if the auto changed down gears/goes to N when decelerating it will not be in gear to stall - what are your thoughts on this?

            So definitely no pink/blue on 3rd plug in my car so I'm stuffed if I can figure this out without the ECU wire diagram.

            Cheers
            Dan.

              All I can think is that Grande and GXL wiring is different?

                Well, back to the book Dan.
                I've found the wires you describe. Top plugs Pink/Blue wire goes to ABS and Suspension control . 2nd plug down Pink/Blue wire goes to the ABS module, but only for the 4Cyl 3RZ-FE engine. 4th plug (bottom) Pink/Blue wire goes to the EGR cut off solenoid on the engine. Which only leaves the 3rd plug (which I used), so if you dont have the Pink/Blue wire in that 3rd plug then thats totally baffling. I can't see how it would be different just between models (GXL/Grande etc). No mention of that in the book. Don't shoot me for this, but are you sure you have the right module? Its just to the left of the glove box.
                You will most certainly know when the torque convertor is locked up. No question. Jabbing the accelerator gives no real rise in the revs (like a manual) as when not locked the revs will rise.
                See how you go,
                Cheers Jamie

                  Haha yep right module even made sure of that, says A/T on the side.

                  What about this - surely it's in the same place even if it is a different colour. If you remember or have it written down, what # pin it is on the 3rd plug (eg looking at the plug as it's plugged in, 3rd wire from the top, right hand side). Maybe they ran out of pink/blue and substituted a different colour.

                  Thanks for all your help with this!

                  Dan.

                    AAAAAlllllrighty then. Mine is the second plug, pink/blue wire. All sorted now thanks for all the help. What a bloody task that was hahaha.

                    Cheers

                      Sorry dan, without pulling it apart and having a look, I can't say exactly which plug position that wire is in. Its pin #4 by the book. Which should equate to 4th down on the clip side. but would'nt take that to task.
                      So, you have it working then I gather from the second message? From the second plug? Strange??
                      Heh, no worries, too glad to help out.
                      I could mention about my home made low coolant level indicator I've got also. The instant the coolant drops off the probe in the radiator the alarm comes on. Every time you turn the key to ON the alarm sounds a short beep, to let you know its working and that the coolant level is right. Can't stuff up an engine... But I won't mention that!!
                      Cheers, Jamie

                        hey jamie something else I have thought of for this you might be able to answer...... in the dash cluster there is the lights for vehicle height. high, normal, lo. which my GX specced prado doesn't use. do you think it would be possible (and easy to access) the trigger wire for the LO light to use as an indicator for when the torque convertor is locked? (LO=locked)
                        I believe the activation button for the height is in the trans shifter area so on the assumption that toyota use the one wiring harness for all spec levels the wiring might be there already. since you have the wiring diagrams would you be able to look it up at some stage.

                          Yeah mate all good. I just studied that photo in your document and matched the plug in my car that has all the same wires as the plug you showed, turned out to be the 2nd plug in mine. All sweet.

                          MRW82, that sounds like a bloody good idea I must say.

                            Thats certainly an excellent idea MRW82. I've had a gander at the good book and asked my Toyota man about the wiring harnesses. He says YES, all harnesses are the same, the plugs just hang around there designated spots. So yours not using the hight control could use the LO light for indication. The "Suspension Control Module" looks like it resides near the glove box near the BCM somewhere. The SCM has 3 plugs go into it. One has 26 wires, one 24 wires and one 30 wires. The wire you would need for the LO light is in the 30 wire plug and is coloured BROWN/BLACK trace. This wire MUST be EARTHED to work, so will require another relay to activate an earth. You cant get activation from the hight control switch in the console as it only sends the signal to the SCM and then it controls the light. Sorry.
                            I havent look at mine to find out (being a Grande it has the SCM) so going only by the book.
                            Hope this can help.
                            I'm going to be away for the next 3 weeks , in and out of internet range (outback) so may be a bit limited for this time, sorry.

                                I'm heading up to DI tonight to catch some of this swell thats meant to be coming over the weekend yipee. Shit it looks like it will be a cold one but fires are permitted up there so I think ill be all good, plus a few stiff canadian club's will warm me up : ) Hopefully the lock up will overcome the heating issue I seem to be having now just driving slowly along the beach. I'll let you know. Cheers.
