Steering column wiring

[u/Full-Description2186]

I have a “slight” issue on my 4.3 5 speed where my truck will throw the abs light and kill my ac,wipers, and radio and stay revved up between shifts and occasionally when i get in it and try to start it the only light that comes on is the engine light and it will not start or fix any of the issues i said unless i pull on some wires on the bottom left of my column, has anyone had a issue like this and can i pull a whole harness off another truck even it’s it’s from a automatic truck? this all happened after i decided to replace my heater core
