Thanks guys for the input. I did tap using the connector suplied with the Edge install kit. And it was very tight fit. I do like the idea of soldering the connection, but that will come later. For right now, the Edge works very well. I am very impressed with how it brings my Cummins to life. I still have the stock transmission, so I don't run it with the Edge turned on very much. Should be getting DTT'd this weekend or next. Looking forward to running the Edge with DTT transmission. Anyhow, thanks for all the input.
