Subaru Launch Switch Harness - Early Model

​

The upper Subaru clutch switch (blue connector on pedal) that is used by the ECU as "clutch switch" is activated at the top of pedal throw, but before the clutch itself is disengaged fully. Using this input for launch control activation will frequently cause bogging as it will not allow a driver to perform a controlled clutch slip at full power.
 

Using our Launch Switch Harness allows you to utilize the bottom (starter) clutch switch into your standalone ECU as a dedicated launch switch. The other clutch switch is retained for shift cuts and other tuning strategies. Starter motor functionality is not affected.

​​

Constructed with new OEM connectors and terminals, TXL 20AWG wire, and PET expandable sleeve with heat shrink labels. Comes with complete instructions and example ECU settings. 44" length.

​

To install, insert the SuperSeal 1.0 pin into an available compatible input on your ECU. Pull-up resistor required. SuperSeal 1.0 pin compatible with all any devices uses the popular 34 or 26 pin TE SuperSeal connectors.​
