I believe you are correct. However, I would have had to remove it myself, pack it up and pay to ship it, and then wait until I got it back. Then I would have to reinstall it myself and hope I could correctly attached all the wires. I've been waiting forever to get this problem fixed. I'm so happy to have it done today and to be able to drive my crossfire! And $79 is way better than the 110 the dealership charged for diagnostics and they couldn't even find what was wrong! I'm glad they didn't charge me hundreds of dollars and say I had to replace the entire RCM. I guess it was my lucky day they were so ignorant. :-)
