Other than power wires, this would set you up to use the amp. This is compromised in that you have to have the headset button engaged, but it will work just fine. You could also tap into the headset harness and solder in your own RCA connectors and this would leave the headset plug vacant, but you'd still have have the headset button engaged. This set up will yield a satisfying pre amp signal to the new amp.

The way I did it, as I detailed in the mentioned thread, was to splice into the actual pre out signals that feed the factory amp. This is more involved and I ultimately removed the factory Honda amp in the process. This is the way I would do it again as it leaves the headset function to function normally. Even though I don't use the headset, I just felt more satisfied doing it that way and it also allowed me to get 4 channels of pre outs as opposed to just the two that are in the headset. Tapping into the preamp signals that feed the factory amp is not that difficult, but it does require some skill in wiring and making connections. Also , for me required removing a fair amount of rear body work. But not bad.
Jimmy, since the headset plug allows for plugging in a combined headset/microphone, I'm guessing the adapter you mention would have multiple jacks on the other end, for 2-channel output as well as microphone input, correct? Just asking so I can fine a suitable adapter.
