Hi everyone,

I bought an RP4-MZ11 and a Kenwood DPX303MBT. I figured most of the wiring with the manual except these:

RP4:
- Blue/White - Amp Turn On Input
- Blue - Antenna On Input

Kenwood:

- Blue/White - Antenna Control/Power Control

Does this mean I have to connect both wires from the RP4 in the 1 from the HU, or just one of them and leave the other hanging?

 

To answer my own question for posterity: Both wires from the RP4 connect to the same wire in the HU.

Now I just have to find a way to get to that freaking side bolt...

 

Just adding a note here for reference in case anyone else is installing a Kenwood in their RX-8.

I'm installing a Kenwood DPX505BT Bluetooth receiver in my 2009 RX-8 (also using the PAC RP4-MZ11 interface), and the radio harness that came with the Kenwood has a brown MUTE wire. I could not find a corresponding MUTE wire on the RP4-MZ11 harness so I called Crutchfield (where I purchased everything), and they confirmed that the MUTE wire from the Kenwood harness is just left unconnected.
