You could try any of the Dodge forums such as that for a partial schematic, , many Auto based forums are aimed at one particular make, some even just cover one particular model.

Sorry I had it all wrong check out my picture pleaseHi Jason.
A little confused with your use of the term "trigger" when referring to pins 30 and 87 on a relay.
Pins 85 and 86 would normally be referred to as the trigger pins.
Pin 30 is the power supply input, so is usually the only pin that needs fusing.
The exception would be if you want to individually fuse each device being supplied from the relay output pin 87.
An example would be if you wanted to fuse the vehicle and trailer reverse lights separately.
A 10A fuse could be fitted at the power source(battery, fuse box etc) for the wire going to pin 30.
Two wires with a 5A fuse in each would be connected to pin 87. One wire would go to the vehicle's reverse lights, and the other wire would go to the trailer plug.
A short in the trailer would only blow the 5A fuse to the trailer plug. The reverse lights on the vehicle would still operate.
The 10A fuse would protect the wire to pin 30 on the relay.
What three devices are being powered by the relay?
2.1A at 12v is only about 25Watts. Most reverse light bulbs are 21W. Are your reverse lights LED?
