DIY: Remove speed cut for Daihatsu Mira L200/L200s

Ok guys, I believe a lot of Daihatsu Mira L200/L200s owner would like to have this done - remove the speed cut for their cars. I came across a pretty nice DIY from the net and I would like to share this information with you guys out there. Actually the process of the modification is pretty straight forward where there is no fancy wiring needed. Continue to read the entire post so that you can have a better understanding on how to DIY by yourself and this may save you up some bucks for the installation fee.

First, open up the drawer and then try to locate the ECU.

Plug out the ECU connector.

Try to locate the green wire and then cut the wire.

If you wish to control the speed cut then you need to connect this to a ON/OFF switch. The concept is when the switch is OFF the wire is connected while the switch is ON then the wire is not connected. With this, you will able to control the speed cut function by a switch.

Here is the final result of the installation/modification. Add in some stickers so that it looks like you got something serious in your car, just like having NOS!!!
