Default Need help with 1996 corvette

I completed an LS1 swap on my 96 vette, but I did it with no details because no one has anything on the internet for this car. I was wondering if anyone knows anything about the original wiring of this car. After I did the LS swap, the LCD display stopped lighting up, so I can't read the speed or the fuel level. Does anyone know how to fix this or have any sort of diagram to assist me. Also the original harness has a portion of the harness that goes through the passenger side firewall and I have no clue what they are for or what they are called, does anyone know what they are for or where they go.
The images are attached below.

You have probably removed wiring that disrupts your CCM, which is what controls the LCD in the cluster. This is one reason why you very rarely see later cars getting LS swapped.

I know that this is some sort of CCM connector, but is there a way to bypass it and light up the LCD directly? Also, do you know the name of those connectors Ex. (C100 which is a bulkhead connector on the driver side).
