Cable 3: Send of amp FX loop to MFX return.
Cable 4: Output of MFX to return of amp FX loop.

That way, you can place your MFX units FX anywhere in the signal chain. Typically, things such as drives and compressors sit in front of the amp whereas you'd place stuff such as delays and reverbs in the FX loop of an amp.
All this only works in case both the MFX unit and the amp have their own FX loop circuits.
