[Biturbos4] B5 tip S4: gray relay in ECU plenum / torque converter clutch

[Ameer Antar]

Does anyone know what the gray relay is for in the ECU plenum? I found that it was not plugged in all the way. Could this be the relay for the torque converter clutch? Is there a relay for that? I ask because I would like to prevent the torque converter clutch from operating for some tests.

Thanks.
