I made a few of these a couple years ago and was looking thru my stuff and decided to sell this excellent condition super clean modded steering wheel. I am including a tested and working Turbo cartridge. $69 + shipping.
This connects to the power supply and the console like the roller controller and you don't need to use batteries. It will however work with batteries also if you wanted to use it that way.
Here is a link to an old thread from a couple years back when I first did this mod.
