It does take a bit of adapting to make it work, but it can be a cheaper route than the full stand-alone controller. The stand-alone is pretty much plug and play, while the factory IDI requires a bit of tinkering. If you're like me, time is far more available than money.......

Well, I ended up with a FREE E4OD transmission the other day......it needs rebuilding. So, if I get it rebuilt what else will I need for the converstion? I plan on pulling a driveshaft from another truck to get the length and yoke right. Now, what all is involved in the controller? Do I just find a j/y controller?
What about the speedo? I see on this E4OD there is a block off plate where the speedo cable bolts to....is there a speedo gear inside there?
Thanks for any help guys........
I don't plan on doing this soon, just want to start researching and collecting parts. Thanks!

I can't really help on the controller, aside from having heard that the IDI controller can be adapted to an older gas or diesel engine that lacks a computer. Not sure how much different it would be for the EFI system used in 85/86. This ECU is not compatible with the trans controller from a later EFI engine, as I understand it.
As for the speedo gear question, pop the plate off and look inside. It wouldn't surprise me to find a drive gear cast into the output shaft. The E4OD came along prior to the electronic speedo.
I've heard that this trans can be used with a V8 conversion in a 93+ ranger by swapping the speed sensor from the trans into the E4OD. The ranger speedo is driven by a sensor inserted into the speedo cable hole, and uses standard speedo gears to calibate. This would seem to indicate the drive gear exists in the E4OD......

Oddly enough, Ray, I was reading this thread to figure out if it answers the question you asked in the PM to me. And, now I see you are "in the loop" already. Good deal. I'll back out and leave you with it.
