Re: D9060 Help Needed

Jim,

I have another D9090 that I have not yet tested nor is it the one 
described in my website blog post below, but it came from a trusted 
source who knew what he was doing, and I have posted pics.    It's not a 
9060, but the relevant parts to this discussion should be wired the 
same.  Note that the LED cable connectors appear backwards, but I guess 
that's how it was supposed to be.

I hope will help with cable orientation.  I don't have a D9060.
