Look at the chart and use the standby PSU wire depending on the version of xbox you have.

Which RF mod do you have, I know back just after Christmas Divinio's RF mod supplier was changed and the wiring was different for the chip due to it being programmed different, there is also another coding done which is different as well so if you do not have the proper diagram you can be a bit in trouble.

Could you tell where you got it and what type is it, such as the chip and receiver or is it a PCB?

To turn it off, just use IGR to return to a hacked dashboard (such as evo-x) then select power off.  No need for the wireless mod  :D  (unless you want to turn it back on.....)

Ah, the doorbell mod.

So you connected the power to the standby and the speaker to the switch. I guess the key would be which type of doorbell unit you got, you would need one with a single ding (Single pulse) to work. The board of the doorbell also must be protected from static or grounding when testing and using.

Test your voltage with a MM and test to see if the frequency is correct so you have a current running through the speaker wire. It is a simple mod but all must be working and tested before use.

If you want an alternative they there are many based off the XBOX DVD remote (The original) or a sony remote.

I use to program my own 12F675's but I'm too lazy now. I do like the look of the XERC but I have not tried one out yet.
