Ok, I have a '99 ZR2. I just bought a hitch for it off ebay. The round tube style that goes up under the bumper and looks clean (basically aftermarket OE). Firstly, any tips/tricks to putting this on? I'm told they're pretty easy to put on, but are there torque specs. for any of the bolts or anything? Secondly, the wiring. My buddy from school said I should get a 7-point connector, because they are more common than a 4-point connector, so, does anyone know how to wire one of those up, and where can I get one?

Any help would be appreciated.
