Thanks for the post. It turns out that it was due to not having the blue amp wires hooked up. I was so desperate after looking at it four hours --so I relented and let my wife look at it. 5 minutes later she figured it out. I'm going to be paying for this for a while... By the way, the 70-5511 worked perfectly for me after jiggling the 8-pin speaker harness around a bit...It's a tricky connector to get the pins lined up.
