A friend gave me this box, but he knows nothing about it. He said his brother had it on a truck and it gave him more power for towing and it was called BD power or something. Not much information.
So I get it and the sticker is illegible. But under the sticker it is clearly marked Van Aaken CAN-bus Pump Controller Carb D-500.

Do any of you have an idea what this chip is and where I might get some specs.
