Description

Holley trans-brake input protection modules allow for an ECU input to be safely connected directly to the 12 V side of the trans-brake solenoid. They are designed to protect the ECU input from damaging fly-back voltage, which occurs when the trans-brake is released. Not using one of them will cause damage to the ECU over time.
