Welcome to CEG
Here is your
link This will give you a useful, detailed howto. I've never done this mod, but many here have, and I've never heard any complaints about this howto. It should be pretty good. Makes sure to do what it says though, use the right connectors, if you don't they may come loose, and that could cause problems.
BTW, the Contour homepage is a good place to look for mods. Click on the Mads/Parts link on the left side of the page, then click on either Howto, or Modifications and Parts.
Also, You may not have noticed this. Fifteen people looked at your post before I answered it. This is not because we on CEG are rude, but because this topic has been gone over many times, and for that reason it is on the CEG homepage. In the future, check the homepage if you want a mod, howto, or have a problem. It the homepage doesn't answer your question, then come here, that's what were for. Before you post on the forum, use the forum search. That may answer your question. Some here on CEG get very tired of answering the same questions over and over. You're new so this is just a heads up. If you continue to post without searching, people may not respond the way you want them to. I'm not trying to be rude, just trying to give you some advice to make your experience here on CEG more useful.
Hope CEG will be a great resource for you.
