My 93 had the potentiometer conversion done.

I liked it, never had any trouble with it. I also liked having the ability to sdjust when the OD would engage.

If you do the swap, just remember a tiny adjustment on the know is all you need to move the OD engage speed. No need to do any real cranking of the dial.

Also as mentioned keep an eye on the VSS, and the plug in connector. These too will cause you to lose OD, but usually the speedo will either not register, or will bounce around if this is the problem.

My 93 went through 2 new VSS units in as many years.
