Hi, I have an 02 sierra hd with an Astro start . Truck was in an accident. Ever since accident , when I use remote start, starter will not disengage. I see a green wire under hood . Could this be tach signal? Trying to fig out where it goes . I did see a posi tap on one of the ecm wires with no wire on it, I was gonna try it , but I really don't want to **** anything up.
