How do you attach a hitch to a 1997 Chevy Blazer?

If you purchase a hitch for the blazer and I'm assuming the 95 thru 2000+ probably use the same hitch(?)there are holes already predrilled in the blazer frame and the mounting bracket on the hitch will bolt up without any problems....i have a 95 and purchased mine from UHaul, it was the newer round style.....only took about 25-30 minutes to install it.Also look up in the wiring(drivers side)and you might find the trailer wires(5 wire or 7 wire)already there....all this makes it a breeze to install your own hitch!
