99 Vssb Pin In/out

[DA BIG ONE]

Any of you know the pin in's and out's at the harness/connector for the 14 pin jumper block VSSB for a 1999 GMC Suburban?

I have someone who suggested I modify the speedo signal before the VSSB and leave the VSSB w/it's original settings so the tranny will shift properly, any of you done this with say a Superlift TruSpeed recalibrator, or?

I have the NP246 autotrac t-case w/3 speed sensors 1) speedo, 2) front driveshaft, 3) rear driveshaft and wondering if I have to modify signal at each sensor too, or?

I know it is in one of the re-print articles that are available in the member's area - I have a copy, but I can't seem to find it.

I been told I can go back to the original settings in my VSSB (when it had 4.10 gears) and modify the signal from the VSS (dk grn # 15 @VSSB socket) to the VSSB to get the tranny to shift properly w/TC lockup at 45mph. Any of you done this, or?
