Digital Dash wire harness Question..HELP!

[WS6GTA]

I have a 88 Trans Am GTA that has the digital dash setup. I recently pulled the TPI engine and sold it along with the ECM and wire harness so i could do a engine swap. The harness that runs into the vehicle unplugged from the ECM and ALSO the digital dash on the passenger side. The harness was clustered together and i did not see a way to seperate it quickly. Not thinking ahead i sold everything. Now i have a digital dash but no harness to run under the hood. I can install a new carburated engine but will not be able to have ANY of the dashboard functions work. What should i do to get everything working again. Do i need a complete used harness and if so where should i try to acquire one??? I am experienced with 12V wiring and could follow a schematic if there is a way to do this without the harness... Either way, ANY information on this matter would be much appreciated!

thanks!
