Getting to the Supra ECU

Getting to the Supra MkIV Twin Turbo ECU.

!!!!! YOU MUST DISCONNECT THE BATTERY FIRST BEFORE INSTALLING ANYTHING ONTO THE ECU !!!!

I'm not responsible for any damage caused if you don't do this

The ECU is located under the passengers feet.
Sit in the passenger seat and where your feet rest, directly underneath is the ECU for the engine and gearbox.
Remove the plastic trim which runs from the right hand side of the passenger door to the left hand side and down into the footwell, the left hand kick panel.
You have one push in plastic locking thing in the footwell area (where you left shin would be) and the rest is just clipped in.
Now remove the two carpet clips which are roughly in front of where your left and right toes would be
You need to remove these before you can lift the carpet up.
Pull the carpet back and you'll see a black plastic cover. It has two 10mm nuts at the bottom left and right which need to be removed
Now lift the plastic cover off. (You'll find the carpet a right pain as it keeps trying to fold back into place)
Move the Gearbox ECU out of the way (The one on the left), it's just slotted in at the top, lift off from the left hand 10mm bolt and pull down. Now just place this unit onto the carpet to hold it down
Next remove the plastic cover from the top larger ECU connector (it covers the wiring going into the ECU and needs to be removed to get at the wires).
Using a 10mm ratchet undo the connector and pull off.
Also disconnect the bottom one as well.
Cut the plastic wire tape wrapping in order to free the wiring loom up, careful not to cut into the loom.

Now you are ready to install the equipment required.
