the cable reel contains about 20 feet of of 5-conductor ribbon wound up in such a way that the steering wheel can rotate with out breaking the connection for the airbag, horn and cruise control. On a DX the the connectors only have three pins, while the EX/LX have 5 pin connectors. Realisticlly the easiest way is to fix this is to buy a new cable reel. but if you are really cheap and handy with a soldering iron (or if you are like me and you fuck up the new one...) you can adapt your DX reel to work for cruise.
