any body with a LB7 service manual for a 2004 duramax alli trans? I need to know the connector color and pin number for the vssb. I am trying to install a TRUSPEED for my 315 75 16 tires.

2001 LB7

ECM connector C2, pins 20 grn/blk & 21 ppl/wht

The wire colors are the same at the VSS sensor located on the output of the transfer case (or trans tailshaft if 2WD).

the super lift instructions say connector c2(red) green/wht on pin 50 circuit # 817 for the 2001 -2003 hd with a 8.1 duramax and a 6.0 my ecm has 2 connectors both with 80 pins one blue and one clear. The blue connector does not have a wire in 50. The clear connector has a green and white in the number 50 pin. These are on the ECM mounted just below the drivers side battery. Not the tranny computer that is mounted on the fan shroud.
