Hi, since I bought this car it has a something plugged into the diagnosis port in the engine bay. It was plugged into the part in the second last picture when I got it and since I have taken it out I notice no difference. What is this for?
Thanks

does it go into the cabbin? if so where does it plug in? it may be something to do with some random JDM thing that the japanese owner installed. i have a really random cellular tracking system that (if set up correcly) supposedly can shut down the car just by calling the car's telephone number. random. i know

Guys thank you for the info. My car has no aftermarket anything! Has a turbo timer only. So its only for a tacho? What type of tacho? I cant see any mount holes anywhere?
So I assume it does not affect the car in anyway?

Where the wire comes through the firewall, have a look under the steering wheel to see where it leads to. Your going to have to trace it back to find out what the other end is attached to.

if that is the case, it is so the turbo timer "learns" how hard you drive so when you turn off the car it can cool down for its "calculated" time
I think you may be correct, as my turbo timer is either 5 secs or some random amount now. But I cant remember if this was always or since I took it out.
I will have a look Justin.
Is that really enough Andrew F? I have seen people do up to 3 minutes.
Any idea where I should replug it. Quite sure it was where it is shown in the second last photo. Thanks guys

Josh, you must think that toyota spends millions of dollars (in our case yen) designing a vehicle. if the standard turbos (turbo) needed 3 minutes of cooling down time, don't you think that they would have added a timer into the ECU? for factory turbos, at most 30 seconds is an extreme. A few weeks ago i took off all the induction stuff and ran the car in "safe mode" just to see the turbo and check its health. after running the car for 2 minutes (letting it warm up), i turned the car off and before i could get around to see the turbo spinning down. it practically stopped. that is the one downside to sleave bearing turbos. when you start going to ball bearing turbos, that is when you need a bit more cooling down time as they spin for 30 to 60 seconds after the car has turned off, and if not adaquitely cooled and run down it can stuff the bearings, that is why i havent bothered to fit a turbo timer yet, as i only give my car a 15 second run down, so i havent seen the required effort to do so

If you are boosting the cars nuts off right up until you park it then yes, perhaps 3 minutes is required.
But for 99.9999% of journeys you will putt-putt around for at least the last 2 minutes before coming to a stop, which is more than enough to prevent damage.
