This controller supports electric power steering pumps from most 2004-2013 Volvo C70, C30, S40, and V50 vehicles.
This controller gives you an easy way to control your Volvo electric power steering pump in your project. Volvo 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.
No longer do you need to compromise with the “75%” power the Volvo electric power steering pumps output without CAN bus. This simple controller has just 5 wires to hook up: power and ground to your existing wiring, and three wires to your Volvo electric power steering pump. Once wired in, pump speed can quickly be adjusted with the turn of a screw.
