The '98 Explorer probably had a 4.0l SOHC engine, but good news is that the transmission bolt pattern is the same on the 4.0l OHV and SOHC engines.
So yes it will bolt in.
You will need remove the flexplate and get a flywheel for clutch operation, not sure on the starter motor, some starter motors were different if there was a flywheel ring gear or flexplate ring gear, call an auto parts store or look on line, if there are different part numbers for auto then starter will need to be changed.
You will need to get the clutch/brake pedal setup from similar generation Ranger.
Also the clutch master cylinder and reservoir, plus the hydraulic line that runs down to trans bell housing.
Your computer will have the CEL on all the time because automatic transmission is computer controlled and it is gone now, so computer thinks there is a problem.
You can get a computer out of a manual trans 4.0l Ranger
You will need to disable the NSS(neutral safety switch) wiring, which is basically just connecting them together.
If your current speedometer is run from the rear axle sensor then all is good, if there is a transmission speed sensor then there will need to be a change.

Just get a pigtail prom the parts store and the speed sensor and splice it into the OSS speed sensor wiring for the old auto. I didn't fool with the NSS when i swapped mine i left the transmission range sensor plugged in and in park and zip tied it to the frame rail. I kept my auto computer and tuned out the trans for emissions reasons but if you get the manual PCM your good may have to tweak the revolutions per mile a bit to get the speedo accurate.

yeah if you don't have the hole for the sensor swap it for a ranger tailshaft that has it its just a magnet that registers the shaft rotation speed. Once its in tap the factory OSS wires its the last sensor on the trans closest to back and its just two wires but the auto plug is different than the manual for some reason so you have to get the matching pigtail.

I had to buy some grade 8 off the shelf bolts for the pressure plate ford no longer carries the 3.0 pressure plate bolts but the 4.0 is still fairly new so they may have them i would also advise new flywheel bolts too there a couple bucks each but mine were stressed when i took them out and could not be reused. the reservoir mounts to the power distribution box under the hood it just sits in there and i used a small zip tie to hold it the bolt i not listed in any parts catalogues for that so unless you find one in a yard thats the only way and slave bolts should already be in the trans just reuse the stock ones. And for the ECU look for the clutch pedal position switch harness under the dash if you remove the auto PCM you lose the pin for the NSS under the truck and will have to use the clutch switch to get it to start some rangers have them some don't mine didn't which was another reason i kept the auto PCM.

There is a thread to wire it if you don't have one but depending on which dash harness you have some auto rangers had it it will be very close to the main plug coming through the firewall and it will be just tucked up in the dash or zip tied out of the way and they used a blanking plate which basically closes the circuit all the time and all you have to do is remove the banking plate and plug it into the sensor on the clutch rod. If you don't have that already under the dash you will need to get the pigtail for it and theres a pin on the PCM that you will need to splice into need a good wiring diagram for it. Its a 4 pin plug i believe but you really only need a ground and the wire to the PCM to complete the circuit.
