Problem solved I did not have to remove the alti. I had to unplug a wire harness that has 6 wires like stated above and one wire runs to a silencer just unplug it OR get a new one like I did in my case and use a 12 mm socket and take out two bolts you will need to know if it is either a 5 plug or a 6 plug this is done by counting the little prongs on the inside of the weather cover installation is in reverse of removal IT is very easy and on a scale of difficulty i would have to rate this as a 1 
now dount you feel less useless you fixed your truck
you should still have a manual
