The Hang Tight PSC is the world first power steering controller that controls Volvo, Mazda, Dodge and Toyota electric power steering systems without reprogramming. This is every product needed to run a Volvo EPAS Power Steering pump in your car. This bundle does not include the pump itself.

Bundle Includes:

• Hang Tight PSC
• Hang Tight Potentiometer
• Volvo Plug and Play Harness or Connectors
• Volvo specific adapter to 6AN

Instructions can be found here.

The Hang Tight PSC is 100% plug and play, it supports multiple pumps/EPAS unit types, no programming required. 

Waterproof design that is fully potted to ensure reliability in the toughest wet and vibration filled environments.

Control assist level with either a trim pot knob or a PWM input from an ECU or controller. You can even use both, it will default to the PWM input when it see's a signal. 
Customize your assist level to your liking, or with the needs of the day.

Each PSC comes with mounting hardware and mating connectors.
Pump type specific bundles can be purchased as a kit, see below for support applications:

Kit Compatibility:

These pumps are medium strength, a bit stronger then the Mazda pump. They can operate in limp mode without the CAN connected, but using a PSC you can control them same as the other units supported.
Integral reservior and remote fill, vertical mount, not the cheapest option.
