I have a 2001 Blazer Lt 4x4 with no toe package. I had a trailer hitch installed by uhaul but they could not do the wire harness. So I was wondering if I would be able to use the harness part 118359 to make it quick and simple. I know it says it's only for the s10 pickups but I thought they were 99% identical. Does anyone know if this harness would work or am I wasting my time? I'd rather not splice if I do not have to.

 

There should be a wiring bundle tucked under the rear of the truck back by the bumper. Its wrapped unfinished wires so you can attach whatever receptacle that goes with your trailer plug:

I'm assuming you are talking about this bundl I found the other day. I do see a connector there as well so I thought that would be where I could attach that I line harness I found but I didn't see the pin layout as of yet. I will unbundle this to see what it has. Thanks!

 

Here is the wiring diagram. If I remember correctly the wires are unterminated from the factory.
