Yes, pin E should have 12v with the key on. You did have the key on, right? Who modded the harness? Have you done a continuity test between the pin E on the trans plug and the fuses in the fuse box?

Ok key on pin E has less than a volt. I haven't had time to work on it but I'm off for 2 weeks starting Monday so I hope to make some headway on it. I had my harness done i think back in 2016 by a guy named Kenny cash, I'm pretty sure was his name. He came highly recommended on the 67-72 truck Facebook page.
