To replace the ground wire on a Ford Bronco, start by disconnecting the negative battery terminal to ensure safety. Locate the old ground wire, which is typically attached to the engine block or chassis, and remove it using the appropriate tools. Install the new ground wire by securely connecting one end to the same point on the engine or chassis and the other end to the battery's negative terminal. Finally, double-check all connections for tightness and reattach the battery terminal.

To wire the starter relay on a 1990 Ford Bronco, first locate the relay, typically found near the battery or on the fender. Connect the battery positive terminal to the relay's input terminal, then connect the output terminal to the starter motor. The ignition switch wire should be connected to the relay's control terminal, and the relay's ground terminal should be connected to the chassis. Ensure all connections are secure and insulated to prevent shorts.
It is the ground wire for the fuel pump. The Red wire is the power wire for the pump. the dark blue is the signal wire for the gauge and the black is the ground for the gauge.
You have grounded to the radio light wire, not the ground. It is a negative wire that is in the harness, and when you turn on headlights you blow the dash lights. Remove your radio ground from the car, and find a new ground. It should be a large black and green wire (larger than all the others). replace the fuse, and turn on the lights...you will see your old ground wire is actually hot now. Common mistake, and it tests like ground wire with lights OFF, but not on. Relentless
