Hello I am getting an upgraded TCU from Ecutune and I removed the two metal boxes under the dash where my left foot rests(not easy). I have to send in my old one and I'm not sure which one is the TCU. One has MQ on the top and is smaller proportionally. The larger one is a shiny silver color with yellow female plugins. Someone who knows for sure please let me know so I can ship it tommorrow. Thanks in advance.
Mike
