1) Any way to turn the odometer back on a 1993 cluster? My cluster with an RPM gauge reads 188k, my truck's gauge reads 167k.

I know it's supposedly illegal, but I'm just turning it back to 167k and I'm probably never going to sell the truck regardless. I won't make that mistake twice.

2) How the hell do you get the speedo cable out of the back? I have everything else off, and I figured out how to replace the module with the trans display.

3) When you remove the gauges, any tips on NOT breaking that little plastic piece off from the rest of the cluster that goes to the trans shifter? I snapped mine off when I took it off the parts truck, but it's replaceable thankfully.

4) My truck doesn't have an RPM cluster in it, when I plug the two plugs on the back in.. will it still work even though it didn't come with it?

5) If I'm putting in red bulbs, is there a film I have to scape off and how do I accomplish that?
 
A friend of mine had a Jeep back in High School and he found he could turn the odo both forwards and back with a cordless drill. I don't know if Rangers work the same but it's an idea.

I just unscrewed my odo from my original cluster and screwed it to the new clusters when I swapped to a tach cluster though, so that's what I'd do if possible.
 
I think the drill thing will work on a 93. You can tell if it will if your odometer goes backwards in reverse.

Just don't do what Ferris Bueller did.
 
Held it by the speedo cable and spun it around to test, it DOES go backwards. Cool. I'm glad it's not some battery gizmo like newer gauges.

Now, anybody have ideas on the others?

You can either swap the entire speedometer or the mechanical guts of the speedometer. The speedometer section of the cluster can be removed independently of the tach and gauge sections.

The speedometer in a 93 is the same whether the cluster is the tach type or the standard 4 gauges with no tach.

I had to repair my odometer in my 86 (it got something in it and jammed up) I ended up popping the rod that holds all of the numbers on out, removing all of the wheels, cleaning them, and reassembling (at the same mileage) Pretty sure I didn't break any laws as my title reads "exceeds mechanical limit" under mileage. Might be worth a try.
 
Mine reads excedes mechanical limit, which will look bad since I'm swapping in a 100k odometer haha. That would mean my title is saying I have over 999k.

Ah well, I'm never gonna sell it anyway.

Any tips on swapping it? I can't see how it comes out..

Do you mean the cluster coming out, or the speedo coming out of the cluster? I know my Explorer had the worlds shortest speedo cable.

Assuming you have the cluster out of the truck, just remove the transparent cover and the black bezel. With those out of the way the individual gauge sections can be unplugged from the cluster base.
 
While you have the cluster out of the dash, it's a good time to do the idiot gauge mod. Replace the switch type oil pressure sender with a gauge type sender and short out the 20 ohm resistor on the cluster. Now you have a real oil pressure gauge.
