you can purchase a easy connector from best buy or napa or autozone they only cost about 19.99$
they snap into the factory harness and have split ends so you can hardwire your radio. actaully i found one on ebay a little more than i thought but check it out. heres the link
correct that is why i STRONGLY "suggest" you search ebay for these types and your bound to find a cheap one that was just a quick search i did as a example.
here is a link just find the system you have. hope this helps.
