One more thing I should add...don't use the "REM OUT" on the 88r. Use the remote wire on the pioneer, preferable through a relay, to turn the system on and off. The internal remote relay on the 88r is notoriously weak and will fail at some point if you're running more than 1-2 things from it. When it goes bad it only puts out a couple volts and will not turn the rest of the system on. For the "remote in" there are two wires on the 88r. I think they are both red. You can tie both of these together and treat them as a single wire. Also make sure the controller is plugged in firmly, as the 88r needs it to be plugged in to function correctly.
