Yep, that page looks just like it. It sounds like you're all set with what you need to hook the empeg up.

In other good news, my truck came in! And I love it. In other bad news, I can't pick it up till probably the middle of next week, because it may have a defective check valve in the automatic tranny cooling system (50 cent part crippling the whole truck), and I refuse to take it till they swap it out. If you have an auto and a diesel in your truck, make sure to read the couple threads on the TDR in the 3rd Gen forum about a possible 2003 recall (it's not a recall yet though).. If that valve gets stuck closed, your tranny gets no cooling and will melt. So it'll be sometime next week (I hope) until I can check the stereo connectors for you. sigh..
