so we took in another truck for our company and im driving it one day and everything on the cluster goes out i dont remember if the radio and hvac unit did to but the back lighting was still lit, come to find out ive hit a wire out of place thats connecting the fouth and fifth ports on the top row of the obd port, when pulled out everything shuts off idk if it has something to do with the guy that owned it before us, he hacked the hell out of wireing to the plow and therse a few things different going on in that truck than others but basically does anyone have any idea what and why thats there, well obv a hack to turn everything on but why is this happening and will the obd port work still? and a fix would help thanks
