should be like installing any other chip on the same version of xbox.
Anyway I find a pretty decent step by step you can control against here:
Wire Install for X-ecuter2.0/2.1/2.2/2.3 Lite & Pro v0.21

HeaderPin Install for X-ecuter2.0/2.1/2.2/v2.3 Lite & Pro v0.21
http://xbox-scene.com/modchips/x-ecu..._diagrams.html
also a few questions about the behaviour you are getting. When the chip is installed can you boot with the chip off and get into MSDash or are you still getting fragging?
It flashes between red, green and orange right?
