Install MPGuino on 1995 850?

Having concluded that I can't use a ScanGauge on my 1995 850, because it really doesn't have an OBD-II port (https://www.matthewsvolvosite.com/forums ... =1&t=56314), I am wondering about installing an MPGuino instead (http://ecomodder.com/wiki/index.php/MPGuino).

It's probably a long shot, but has anyone actually installed an MPGuino on an 850? If so, any pointers on installation and calibration?

Many thanks, again,

Still puttering away on this when I have the time. I think I can find a fuel injector signal wire, but I'm not so sure about the vehicle speed sensor. Is it on the gearbox for standard shift (my car) as well as automatic? What am I looking for?

On a '95 the VSS is on the bottom center of the transaxle but it is an analog sine wave signal. If you need a digital pulse train then tap into the wiring from one of your ABS wheel sensors. The frequency is all the same.
