92 Comanche speedo

[Aidenmoreno3]

I have a 1992 Comanche that I took to an electrician and, stupidly, I let him take the interm portion of the speedometer harness. 
 

Now I'm trying to fix my speedometer and can’t figure out which portion of the engine harness is the speedometer.

 

important note is my cars engine and trans were swapped by the previous owner with a 1995 jeep wrangler. 
 

I’ve attached some pictures of what I think are the plugs since they’re in the right location. Let me know if you guys can help in any way. I’m trying to find out what plug type goes to the speedometer

It’s that area and that general shape of connector, yes, although I think the four-wire connector is for the transfer case position switch. I thought it was only a two wire connector, but I could be wrong. I think the speed sensor changed from a 2-wire to a 3-wire sensor sometime between ‘92 and ‘95 but I don’t know how that would affect the connector. I’ll have to double check mine when I get home.

I believe the single wire connector is for the engine compartment light - if equipped.

No, I was wrong  

So turns out it is a four wire, this is a terrible picture but I think you’ve got the right one. 
 

The under hood light connector is a two-wire.

@gogmorgothank you for the help! I pulled the interm harness off of a 1995 Cherokee and that one was terribly wrong. So is it safe to assume if I was to find a 94 or older that it should have that same 4 wire hardness?

Which end of the harness was wrong? Do you still have your original speed sensor in there or the one off the YJ? There’s a few different part numbers for the speed sensors for ‘91-‘93 and another one again for ‘94-‘96. 
 

I want to say I went through this on my ‘91 when I swapped to an NP242 out of a ‘93. I had to reuse my MJ’s speed sensor because the ‘93’s wouldn’t work with the MJ. It might have been a ‘94 though, it was a long time ago. At any rate I remember wanting to use the XJ’s speedometer gear for a better tooth count than my MJ had, but then I couldn’t use it. 
There was also something about the 4x4 switches that I think is tied into that interim harness, although my memory’s a little fuzzier there, it could be part of the trans harness, not Tcase. The CAD models use a switch on the CAD, but the later models use an electronic switch at the transfer case in place of the big vacuum mess. When I did it I think it took some effort sorting through to figure out what I needed to do, and I can’t quite remember what all I did ten years later, but everything plugged together in the end. But then I was going from XJ to MJ, not involving any YJ parts.

That does appear to be the correct plug. 

Here is a screenshot out of the 91 service manual showing the plug and the wires that go to the speed sensor. 

Those are the only 2 wires I hooked up when I did the fuel injection on my Eagle as I kept the original speedometer. Fairly certain one of those other wires goes to the cruise and the other to the speedometer. Might be wrong on that.
