- In theory, theory and practice are the same. In practice, they are different.
That is correct.
Once the circuit is supplied by a fuse, it rarely ever goes through another fuse in automotive circuits.
There is no reason for a relay since the reverse lights are the only load on that part of the circuit and they dont draw much current. So, basically, the flow of power is this;
Fuse at SJB >> DTRC>> reverse lights >> ground
Sometimes a fuse will power several similar circuits. Don't let that throw you off track. And, yes, the circuit will go through multiple connectors and splices. This is necessary to make it possible to install the wiring through the firewall, frame, other tight spots at the factory.
