Believe it or not it's inside the gas tank.
It should be located on the drivers side frame rail near the rear of the motor. (This is under the vehicle)
drop the gas tank and it is the large hole with a lock ring that keeps it sealed
The relay it self is in a set with three or four other relays on drivers side top inner corner of the fender, its in a box so you'll have to wiggle that off first.
Yes it does.
