Ok, I have been doing all the searches and have come up with one solution, Soundgate Digistar. I am looking for a interface for the h3 and don't really want to cut any wires. Here is a bit of info on what I'm doing;
2006 hummer h3 with monsoon package
installing Pioneer N-3
installing front and rear components
installing a 2 channel and 4-channel amp
and sub
Will this work for the N-3:

I found it on ebay, is this the right one for me.
If anyone can give me info on this it would be great.
Thank you.
