Hey guys. I'm swapping an '09 LS3 with a T56 using a PSI Conversions Harness.

Do I need the TCC switch? I don't see what it would do with the new trans, but then again I'm not sure if the newer style ECU's have some special purpose for it.

With the T56, there's obviously no torque converter. But that switch (part of the brake light switch) is used to disengage the DBW cruise control, along with the clutch pedal position switch.
