I bought a used OEM security system, an everything went just peachy except for one thing; the LED connection. THere's supposed to be a small fitting on the end of the + LED wire that goes into a hole on the back of the 16-pin connector that plugs into the security system 'brain'. However, I did not get this, so I couldn't hook up the LED. THis has recently become a problem, with me trying to figure out what puts me into what mode, and the LED is the only indicator for some modes. Is there any place other than the dealer that I could get this, and how much should it be? Thanks.
