G Scale GP30 electronics arrived today. Still have power supply, and 1 decoder that are not here yet! Couldn't send at one time I guess. Anyway, Does anyone have an EASY diagram on HOW to install Phoenix sound in a USA Trains G Scale GP30, track power?? All the instructions say, is how to hook up baattery(ies). I do NOT run, or trust batteries. Don't want to charge them every hour! Think I have everything I need, except proper connection instructions. If anyone has easy to understand installation instructions, it would be much appreciated! Was hoping for QSI board(s). Since that's what the GP40's use. Anyway, any help/information much appreciated! Thanks.
