Are you trying to run this with that TRX switch you rewired? Maybe you should try the old 350x switch and see if that works? I hope you didn't wire something wrong. You did say the 350x switch worked for off an on but just not the lights right? Go back to what you know worked first and see if it will start. Then we'll go from there. Start with basics and work to the harder stuff, not the other way around.
