An aTRE is an automatic TRE. It is designed to turn itself off electronically when you put the bike in neutral so cold starting with a TRE isn't an issue because the TRE is off.
How a TRE works is it tricks the computer into thinking it is in a certain gear all the time. With the SV TRE, you made the computer think it was in 5th gear all the time by feeding the computer a certain resistance for the gear you want. When you open circuit this connection, it thought it was in neutral. So I used a transistor and the voltage feeding the neutral light to act as an electronic switch, so when the neutral light came on, the switch opened causing the open circuit desired.
