I am trying to install an aftermarket part on my wifes car. The problem I am having is that I can't find a wiring diagram that will tell me which wires are for which set of speakers. I need to find the two that are for the right side and the two that are for the left side. That way I can tap into them and install the adaptor to run an aftermarket set of subs with the original mansoon equipment.

Try these folks, www.crutchfield.com. Hope that helps.

Thanks I will check it out
