It's not too hard, yours would be similar to mine. I have a '94 4.0L.
You could check the tech thread to see if there's a thread on it.
The Ranger V6 is fairly simple to change them on. Working from memory, I believe the rear passenger side is the toughest one. The rest are pretty straightforward and easy.
You need anything else just let us know.

When I changed them in my 99 it took alittle work, maybe because my hands are the size of bear claws. Job is alot easier if you have a flex-head ratchet and one of those universal-joint things for the extension.

The process is pretty straightforward, although the right side on a 4.0 can present access challenges (wheelwell is always an option, as is a swivel, and also a peanut plug socket with a hex head + the use of a box wrench). I would suggest you do one plug wire at a time unless you have the firing order handy or know it by heart. Don't forget to apply a dab of silicon to the rubber boot on each end of the plug wire.

it would have to be easier than it is on the 2.3l engine. I think they designed those engines to test your patience.

Hey guys, does anyone have a wiring diagram for plug wires for those who have a bad memory? Thanks!

For what engine?
In the Haynes:
4 banger:
3 - 1
2 - 4
4 - 2
1 - 3
Cylinders are 1-4 with 1 being the fowardmost
Distributor 3.0L V6s:
Engine:
3 - 6
2 - 5
1 - 4
cap:
looking down, the screw towards the front on the part sticking out (it that makes sense), right above it, going clockwise:
6, 1, 4, 2, 5, 3
Distributorless:
Coil Pack:
3 - 4
2 - 6
1 - 5
Engine:
3 - 6
2 - 5
1 - 4
4.0L V6:
Coil Pack:
3 - 4
2 - 6
1 - 5
Engine:
3 - 6
2 - 5
1 - 4
Hope it helps.

Interesting that you bring up the Haynes and the 4-cylinder.
There was a thread a little while ago where CowboyBilly9Mile posted a diagram with the wires for cylinders 2 and 3 transposed (on both coil packs) from what RangerPilot posted, which solved a problem for someone who was following that diagram. I checked my Haynes, and found that the diagram appears both ways, although in different places. So, out of curiousity, I popped the hood on my '97 2.3, and it is as RP posted above. My truck doesn't run quite right, but runs WAY too well to have those wires on wrong.
I don't really have an explaination, but I figured this thread might pop up in a fair number of searches...
I guess the moral is to write down what's under YOUR hood before you start messing around with it.

That's true...I do remember that thread. Seems some of the Haynes were incorrect.
I'm not worried about mine (I have a 4.0L V6), but I don't want to give somebody the wrong info, either.

Thanks! I needed the one for the distribulatorless 4.0 v6. Specifically the 4,5 ,6 order. I thought it was odd to have the driver side 3 out of order numerically. Guess its right that way after all.

Yeah when I was typing it I looked at that like "hmm....that's kinda odd." Knowing the Haynes problems, I looked at my truck, and it's the same way. Just one of those weird things.
