Looking for a brave wiring expert to help with wiring

Hi,

I have a '75 Duster. The PO sprayed he wiring harness with tar. When we took the harness out we took pics but they have been lost. We tagged some of the stuff but we didn't do any more when we pealed off the covering (and to disconnect some of the pieces) to rid the wires of the tar.

We later cut some pieces to help tangle out the mess.

We are making changes under the hood that will get rid of some of the boxes.

I am now working through the wiring harness diagrams in the service manual and I am running into brick walls.

I am looking for some one that I can send pictures / questions to and I navigate this mess.

Oh, our budget this year is blown so buying a painless or whatever new harness is not an option.

Thanks
Ian.
