tow hitch wiring harness

hey everyone i'm a new member... been readin this stuff for some time, just now registered.

heres what i got.  1994 4door s10 blazer 4x4 vortec 4.3.  factory all the way around- got later model wheels on it....anyways.... got a question for yall right off the bat....

I have a reese receiver hitch on my blazer.  i want to get wiring harness to run trailer lights from it.  i want one of those kits that involves no cutting or splicing.  they make kits like that for many many vehicles.  however, they only make one for 2 door blazers from 1994.  it specifically says "2door only"

I am wondering if i should try it and if it doesnt work take it back, or if all of you have tried it and know it is a waste of time to attempt.  or.... if anyone knows of a place or company that makes that for a 4door.  hopkins makes them for almost every type of application except 92-94 4door blazers!! ahhhhh!

 I am GUESSING the 2door kit will not fit on your 4door truck because the wiring won't be long enough since it is made for a shorter vehicle.  I would look on google or eBay to find what you want.  That's my $.02.
