I purchased a evo all with gmt 4 harness for my 2008 Chevy express. My van does not have a factory fob because it has manual locks and window cranks. Can I use the start stop signal wire (a13) yellow/brown to start the van. I searched around and read that a negative pulse will activate this wire. I follow what little instructions that I could find and all it does is turn my dash and headlights on but does not proceed to start the car. Not sure if I have to change some options with the flash link updater or if it will work at all since I don't have a fob. Thank you for any info
also when I ground the start stop wire. The blue led blinks 1 time and then doesn't do anything else
