It's for a 2002 - 2004 Dakota.... Don't know if it'll work in your '06.
That I don't know, (don't take my wiring numbering as gospel either) your best bet is going to be to find a wiring harness schematic and match up the colors on that connector. It will also tell you what wire you need to splice into down at the computer by the drivers' left foot. I can't get to my truck right now to tell you that. You will want some of those add-a-fuse taps for the B+ and Ignition wires in the fuse box. A ring terminal to pick up ground near the fuse box.Looking at the computer
Hey so looking at the computer picture at the top, which one is pin 1? Right side (that has the red wire) or left side?
