Ok, I have a 1978 K-10, 350, short bed , and i found this wire just hanging out under the dash. I was hoping someone could enlighten me on where it is suppost to go? It apperas to have a staple sticking out on the one end. when i unplug the solid purple wire the truck gets power, but will not turnover, until i plug it back in. So does anyone know why this Staple (unknow) would be stuck in the end, and shouldnt it be pluged in somewhere? Thanks for advice in advance.
