1998 2500hd P/u Need Help...please!

[1998HDXCAB4544X4]

I own a 1998 2500 HD extra cab with a 7.4L, 4x4, auto. I redid the entire truck from the frame up, including a cab swap. I swapped to a 1997 1500 3 door extracab. In my haste, I clipped the engine harness coming into the cab on the passenger side firewall figuring I could just splice in the new cab...Wrong. Also in my haste, I scrapped the old cab without removing the dash, or harness for that matter. here is my problem....

 

The 1998 2500hd 454 harness at the firewall has a different configuration than the 1997 1500. I dont have the old dash harness from the original cab, or the part number, or any pictures of what was under the original dash (control module, distribution block, etc.) I need to know what harness (and whatever else) I need to purchase to rewire the 1997 dash and make the 1998 engine harness work. Or if someone has a 1998 2500HD dashboard and uncut harness for sale...either way...This is the only thing holding up my truck from getting back on the road, and I am dying to drive my bowtie...Thanks in advance.
