Hey guys,

So after a long time away working on my RX8 i've come back to my Lexus IS200 daily. I'm currently looking for a complete ECU diagram for each wire.

I'm looking for, 

12v ignition wire,

RPM signal wire,

Crank shaft sensor wire

Ground (Most likely use a bolt in the engine bay for this.)

I've searched online all day with nothing but gibberish coming up and dead links.

I've found countless IS300 diagrams which seem to be different. I've tested and failed.

Has anyone got a list for the 4 plugs on the top of the ECU? It would be very handy.




EDIT: After sifting through tons of pictures i think i have a part list of what i need.

Working from front to back of the car i have,

A-B-D-E plugs.

12v power seems to be from Plug A Pin 1

RPM seems to be from Plug A Pin 12

Crank Angle Sensor seems to be from Plug E pin 23

Ground most likely to the chassis.

Can anyone confirm if i'm anywhere close to the correct pins/plugs? This is all i can workout looking at random diagrams online which seem to be part complete or taken from SXE10 engines which are 100% different apart from the power.

Has anyone got a list of ECU pinouts? It would be very handy. I've seen multiple post's around that link to a couple of places but the website/link is dead so not very helpful.

      Hi, new to forum, there may be an already existing thread but I cannot find anything......ANYWHERE! I need an ecu pinout for a 2001 is200 using a 1gfe with an ecu number 89661-53200. I need this pinout diagram and expertese to fit a bee*r limiter basically because I want one and I like being a loon in my car. There are people who hate/disagree with them, however I would like one in my car and I would appreciate help fitting it.
      any help appreciated.

      Hi everyone. It's not Xmas but might as well be.
      I had a problem with a worn rear wheel bearing. The car had been used to tow around an exhibition trailer in its early life and at 175,000 miles started to complain. I'm not complaining as 175K miles is still good value. To look at car is immaculate inside and out. Still gives 40MPG and I am still in love with car after 7 years of ownership.
      Changing the bearing I managed to damage the ABS sensor: and when trying to remove the broken sensor, I damaged the sensor ring. To make matters worse, thinking I could repair the ring, I removed the sensor ring.
      Duh! What was I thinking.
      The friend, whose garage I was using to do the work, suddenly needed his garage and so I had to move. I drove the car home and parked up.  On the way home. No Speedo. P/S Red light on even though power steering feels okay.  ABS light on. Engine light on. VSC complaining.
      So now I have a replacement hub, with ring, new ABS sensor fitted and all on the car.
      But all the lights still on.    I have tried removing the Battery over night.  All lights still on except Engine light.
      Any one with any thoughts before I troll off to my Lexus dealer who will want more money than they value the car at to plug in their OBD reader.

      Newbie and Know Nothingbie......any help greatly appreciated.
      My check engine light has appeared for the very first time since I owned the car (6 years and 40,000 miles) so I'm unsure if I need to take it to an official dealer or a regular mechanic to diagnose the fault.
      The car appears to run ok for the very journey I did to get it home.
