Just finished installing my empeg into my 2001 Dodge Ram Cummins 3500. The install went great due to the PAC OEM-1, and sounds great. The only bad part was buying it. I can't recall the last time I've had service as bad as I recieved ordering from tune-town.com. I should of recieved the adapter within 3 days if they had processed the order in a timely manner, but instead it took them 5 days to let me know that I had provided them the wrong billing address. Except I hadn't. They had the right address all along and it was some mistake they had made. It took them 2-3 days at least to respond to any emails, and in general didn't seem the least bit interested in making things right or having me be a repeat customer (you can bet I'll never shop there again). I finally got the adapter after about a week and a half.
Just a warning, YMMV as always.
Off to go sit in my truck in the driveway..
