Once you have the ECU on the top of the car you can now start to unplug the connectors.

1

Unclip the two rear and front clips which will allow you to take the top off the case.
2

Now you can start to unclip the connectors start from the right hand side.

The first plug just lifts upwards by pulling.
3

The next plug you need to depress the tang and pull the lever arm over, this will lift the plug up it's self.

5

With that plug out of the way move onto the next one.

8

Then onto the last but one plug.

The last plug is the same as the first it just pulls upwards.
11

You can now slide out the ECU.

You can check the pins for corrosion before you send it off for what ever reason you are doing it for.

In the post with it and wait for it's return and repair or upgrade by one of the Guru's above

Hi Steve. Do you have to disconnect the battery before you take the plugs out of the ECU? Think I read somewhere that you have too.

Hi Dave.
I have never disconnected the battery, but if you feel it is safer for you then by al means do it, no ignition on or key in the car you should be safe enough

Same when i undo the SBS connectors under the seat never ever disconnected the battery, maybe i am play Russian roulette ? but i think it's safe if the car as powered down for at least 30 minutes

Thanks for that info Steve. Also Big Russ agrees with you, so it must be ok.
