Sorry i cant help with the pinto but i have fitted one to a zetec and found it straightforward but the zetec doesnt need a trigger wheel cos it allready has a crank sensor
tps is in my opinion nicer than map it is just a bit neater and doesnt need vac tubes coming from each inlet tract then into a damper chamber then into the megajolt, i converted mine from map to tps
If you speak to triggerwheels they will supply everything you need for around about £200
