Which wire for speedo from computer??? Have a 2003 Yukon 5.3/4L60E, stock wiring harness. Using the Dakota Digital SGI-5 interface to a Haneline speedo.
On the PCM Green connector
PIN# 20 Lt Green/ Blk VSS low
PIN#21 PPL/White VSS High
PIN# 49 Yellow/Black Vehicle speed signal
PIN#50 Dk Green/White Vehicle speed signal
I currently have the PIN#50 hooked to the SGI-5 input, the green light is on but nothing else. Instructions says no VSS signal to the unit. Dakota Digital was no help.

Pretty sure its pulse.
This is from the instructions.
Early Ford Transmissions - the pulse signal generator will thread directly to 32-48 torgue tube type enclosed drive lines.
Computer Transmissions - signal obtained from computer systems. Refer to factory diagrams.
GM Computer Controlled Transmissions - Late 700R4, 4L60E, 4L80E consult factory manual or a wiring harness manufacturer for a location of signal source. A signal translator is required.
