Final Wiring Harness Inspection and Research

GMT400 Suburban Frame Off Build: Body Removal & Getting Ready for Frame Paint! (What To Remove)
What happens here
After removing the engine, the creator notices that the main wiring harness (the engine side) is still partially connected to the body. He realizes that the plugs for the factory PCM (Powertrain Control Module) and TBI (Throttle Body Injection) computer run through this harness, which is integrated with several other systems inside the vehicle. He learns that to fully detach it, he would need to go inside the vehicle, dismantle the glove box, unplug the harness from the computer, and then pass it through the firewall. He decides to leave it dangling with the body for now, as it's not connected to the frame anymore, to research the best approach for the new engine management system later.
Goal: Confirm all wiring harnesses are disconnected from the frame and plan for future wiring needs
