I have researched as many places as I could scratch up for an old truck. I have all the interior panels and dash removed for a stereo install, new window sliders, etc. With the help of others in this forum and some probing with MM, I have found all of the wires listed at multiple alarm sites. I was assisted on a previous install of this alarm in another vehicle and anticipate that will make programming and use easier. The temperature was 110 degrees today and would like to utilize the window features. I am replacing a rear window, and was hoping to prevent another break in. I have owned this truck for over twenty six years and it deserves my love. Any help, corrections with my flawed thinking, and recommendations are welcome. Looking for approval before I start soldering. Measure twice, cut once seems to apply to many efforts. Thanks.
