HELP!! YJ to LT1 Fbody electrical issues with howell harness HELP

O.K. folks I'm pulling my hair out trying to make sense of this Howell engineering harness. I pulled out my 2.5 motor and ax5 and put in an lt1 motor with ax15 trans, with the help of advance adapters parts. now on to the electrical.....

I bought the lt1 TPI street rod harness with ECM. The howell harness to the lt1 components went in super easy. I just cant figure which wires from the firewall plug coming into the engine bay do i need to connect to the new harness to activate the fuel pump and ignition switch stuff.

I went to Howells website and there was nothing specific about this particular application. I was hoping that someone here has done this and can save me the agony and time being spent on this project. Seriously in dire straits here.
