This controller supports electric power steering pumps from most 2011-2013 V6 Dodge Durango, Jeep Grand Cherokee, Chrysler 300C, etc. For example, Dodge part number 52124998AH. These power steering pumps have a larger motor and pump compared to Volvo EHPS pumps.

The output of the pump is an uncommon side seal hydraulic fitting, one way to convert this to a 3/8JIC fitting can be found here. https://reformmotorsports.com/dodge-jeep-chrysler-pump-modification/

This controller gives you an easy way to control your Dodge electric power steering pump in your project. Dodge electric power steering pumps are an inexpensive way to add power steering to your race car, rat rod, or other project where a typical power steering pump might not be feasible.

Compared to traditional accessory driven power steering pumps, electro-hydraulic power steering systems have the added benefit of being able to adjust the power steering feel and amount of assist by changing the pump speed.

The electric power steering pumps from these vehicles will not operate without valid information from the vehicles CAN bus, this controller will send the correct data to the pump to force it to operate. The controller has just 4 wires to hook up: power and ground to your existing wiring, and two wires to your Dodge electric power steering pump. Once wired in, pump speed can quickly be adjusted with the turn of a screw.
