I know Jamas was great enough to help me with the exchange hand off, but I don't think anyone else jumped in at the time. One issue we had was they want the vin number of the vehicle that the unit is going on, so we did some creative shipping (I filled out the form and had Jamas send it with his unit, then he filled out the form and I sent it with my unit). He was a great help for me and I hope you can find someone else to do the same for you. It has been almost 10 months and I haven't had any sign of an issue since. If you search for ABS module you will see one titled "2005 Durango ABS control module fits" that is the one where we discuss the hand off.

I never tried driving without the unit since I didn't have to remove mine, but since you are disconnecting several lines I would not suggest it.
