Troubleshoot and Temporarily Repair Truck Electrical Issue

What happens here

On the way to pick up the new plow, the truck begins to stall intermittently, losing power and then regaining it, especially when hitting bumps. The driver pulls over and opens the hood to inspect the engine bay. He suspects a loose ground connection or crossed wires related to the recently detached plow's electrical system, potentially affecting the trailer connector circuits or other truck electrical functions. He attempts a temporary fix by visually checking and wiggling the electrical connections and possibly tightening any visibly loose terminals under the hood to restore stable power for the journey.

Goal: While driving, the truck experiences intermittent stalling and power loss, suspected to be an electrical issue related to the plow wiring, which is addressed with a temporary roadside fix.
