Hi,

Is there a wire in the brake switch in the Impalas for this wire? It needs to be connected to a ground.


Thanks,


Chris L.

The LS Harness requires a TCC brake ground to release the converter when the brake is pressed. I need a wire to connect to on my 94 Impala SS. I was thinking maybe there was a wire on the brake switch since the car came with cruise control.

yeeeeeees, I get that.

LS is a pretty wide family these days.

What PCM are you using and what was its original application ?

Example, mine is an E67 ECU using a GMPP calibration based on 06 CTSV.

"411" with 2000- 2002 F body calibration is something completley different.

Without opening my manuals I don't think there is a "grounded brake released" switch but am thinking easy work arounds
