wiring diagram for chevy suburban c/20 w/ a/c front and rear

Having wiring problems with my 1972 c/20 suburban. I thought it had original motor in it but it turns out I have one from a 76 truck. Original came with points and this has hei. How do I make the wiring work correctly? On a limited budget, don't really want to buy new harness. Can someone please help me with a diagram with changes need so u can start the Burb with the key. I can only start it with jumping starter to battery. Thanx.

There are standard wiring diagrams in the FAQ section:

And figuring out HEI wiring is as simple as typing "HEI Wiring" into the search box:

Thanx Im reading it now. I hope can do it. I replaced a few wires that were melted together. But still didn't find the problem. I hope I can do the rest.
