I picked up this racing wheel and pedals for DC at a local thrift store, all for the amazing price of only $1. The only thing about it is that Interact designed this peripheral to plug in with an electric power adapter to activate the rumble feature. The thrift store did not know where the power adapter got to, and I do not see voltage, amps, or polarity listed anywhere on the wheel or pedal assemblies. Can anyone fill me in on the power and polarity requirements for the Interact Concept 4 Racing Wheel for DC? Maybe an old Genesis or SNES adapter would do, but I don't want to risk cooking the internals with the wrong polarity. Thanks.

Radioshack has a bunch of different sets of plugs and wall warts, just go buy a plug that fits and try a few of the different power supplies out. They have an awesome return policy, so if it doesn't work you can easily get your money back. I've done this for guitar pedals.

It requires a specific voltage and milliamperage power supply. Unfortunately my own Interact wheel is in storage and I don't recall what the specifics for that power supply are. DO NOT GO PLUGGING RANDOM POWER SUPPLIES INTO IT!
