Thanks for the help all. I did take a look at it last night and did some tracing with my meter and found there was no hot leads from the honda side so I got curious and pulled the radio. For whatever reason, the cable was pulled out of the back of the Head Unit so I reconnected it and it now controls the changer fine. Sounds good too. I will have to check into the left/right swap that y'all mentioned with the honda/alpine mbus connection, but its going now anyway.
Thanks again for the help with the pin outs. Now I will have to try
something hard down the road: hooking an mp3 player up like you guys do
thanks
