From memory these are codes for cylinders 1,3 and 5... right beside each other.

You do realize that any pertinent info about your truck is missing from this post...... but I'll go out on a limb and opine that your truck is pre-updated UVC harness and you have an undercover harness that is coming unplugged... right hand (passenger) side, FWIW...
