F9T-SSR-993  99361522701 99361522702  Replace you old failure-prone mechanical DME relay with this premium Solid-State upgrade. Because it has no moving parts, it cannot "wear out" like the original or aftermarket relays do. This optional feature allows you to instantly know the state of the DME Relay. It features four LEDs that are directly connected to the critical inputs and outputs of the relay. All four LEDs must be illuminated for the engine to start and run. If one or more LED(s) are off , there is an issue with the corresponding circuit.

Ignition SW – (Yellow) Input signal to power up fuel injection system and enable fuel pump control.
Fuel Inj. Power – (Red) Output indicating the fuel injection system is powered up.
Ctl. Fuel Pump – (Green) Input signal indicating the DME has commanded the fuel pump on.
Fuel Pump – (Blue) Output indicating the fuel pump is powered up.

Please follow these installation instructions;

1. Keep the relay in the anti-static bag.
2. Remove the original relay from the Central Electrics plate.
3. Touch the body of your Porsche, preferably exposed metal.
4. Remove the Solid-State Relay from the anti-static bag
    a. Avoid touching the pins if at all possible
