I bought this a few years ago and never had the opportunity to use it. The actual one I have is black and has all the necessary wiring as well as a switch to enable you to choose between the specified boost levels. Still have the original box that it came in. I'll get pictures up as soon as I can today.

If you have any questions please send me a PM with your email or number and I'll get back to you almost immediately. If you do decide to purchase it I'll do my best to have it shipped out within the day.

Asking $175 shipped. Someone needs this!
