Where can I find a TCM wiring harness for my 2.3l Mazda 3

I bought a 2007 Mazda 3 2.3 liter for $500 bucks, with the pre knowledge that it had an electrical issue. I've replaced the TCM and repositioned it. However, I saw somebody had cut and splice wires trying to fix the harness ( probably bc its so expensive to replace) So now I am trying to find the tcm wiring harness to plug and play. Ive went to multiple junk yards, every one of the tcm harnesses have been cut out, go figure.

Anybody have any ideas how to get this harness for reasonable or even what its called so I can search for it more specifically. I believe its the TCM wiring harness that connects to the TCM.

Thanks in advance!
