MAP sensor input voltage?

Guy at work has a '89 XJ I don't have the fsm for (mine a '96).

The symptom is a high idle that slowly climbs as the car warms up.

His MAP sensor input voltage is 12 volts (!) and I know it should be ~5

The next step would be to make sure someone didn't mess with the harness and check the output at the ECU (or whatever its called on a '89), but I've found conflicting info on the web about the MAP pinout at the ECU - some say it's 13, some say it's 16. Anyone know which is correct?

Thanks
