This question cannot be answered without further information.
Please ask this question again and be sure to say where the fan controller relay is fitted: is it in a car or other vehicle? It in a home? What make is it?
On a 200 amp or any size service the ground wire is easily identified. Look in the distribution panel for the neutral bus bar. This is where the service neutral (white wire) is connected to the distribution panel. There you will see a bare copper wire connected to the same neutral bar. This is the ground wire that is connected to the ground rods out side of the house.
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.
Not looped but connected to both ground rods and then connected to the meter base.

Ground wire can be appropriately bonded to the neutral and cabinet at the service box by connecting the neutral and ground wires from the feeder wires to the neutral bus bar and the ground terminal located on the same cabinet at the service box. White wire (neutral) must be connected to bus bar and bare wire must be connected to ground terminal in the same cabinet.
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
Yes, if there in no ground wire that is acceptable on a home with no ground wires.
The speed sensor wire is connected to the speed sensor and goes to the speed sensor relay switch. The speed sensor relay switch is connected to the computer by a separate wire.

yes theres an braided ground wire that bolts to the transmission bell housing
ground wire, all the metal on the car is where any electricial device can be connected to.
The ground wire should go from the dryer directly back to the distribution panel. An external ground wire is not required. The ground wire that is in the cord set that is connected to the frame of the dryer and the ground wire that is in the feeders coming from the distribution panel, that is connected to the ground terminal in the dryer receptacle, is all that is required to satisfy the code requirement.
Positive post of capacitor is connected to the heavy amp cable. The ground terminal (or case) of the capacitor is connected to the car's ground or a ground wire that leads to the car's chassis. That's it.
This would be a standard procedure for any 12 volt negative ground vehicle. Using a typical generic automotive 12 volt relay, notice that the connections on the relay are numbered 30, 85, 86 and 87. Each connection has a generic function. You would wire a relay for aux lighting as follows, Number 30 would be connected to a 12 volt fused power source from the battery. Number 87 would be connected to the positive lead for the aux light(s) not to exceed 300 watts per relay. Number 85 would be connected to chassis ground. Number 86 would be connected to the 12 volt lead from the manual control aux switch.
