HELP!! 5.3 LS/ 4l60e/ Intellitronix gauge cluster

[c10rike]

I have an 86 square that I have installed a 5.3 LS/ 4l60e out of a 2006 Tahoe, Runs, and drives.
Just installed the stock 86 painless wiring with LS swap kit.
I have no tach or speedo reading, on the intellitronix gauge cluster. (0.00)
I just bought a Dakota digital SGI-100BT to wire the speedo and the tach to the intellitronix gauges.
All of the EMC diagrams for the VSS do not match up with what I have to tap into it.

How do I find the wiring on the ECM for the speedo and the tach?
How do these 2 items talk to the intellitronix gauge cluster?

Thank you to everyone who helps in advance!!!

have you reached out to Intellitronix?  Their cluster should come with compatible pieces to make this work.
