DO NOT touch it yourself. It's very easy to screw 'em up.

there are three differant IDMs 100v 110v 120v. The OBS (94-97) powerstrokes had the 100v IDM. and the PSDs (99-03) had 110v to 120v IDMs.
For the 100v and 110v you need a 75.0K Ohm (75,000 ohm) 1/2 watt 1% tolerance Metal Film resister to make it 140v.

The 120v needs a 73.2K Ohm (73,200 ohm) 1/2 watt 1% tolerance Metal Film resister to make it 140v

DigiKey sells the needed resisters
75.0KX (Violet-Green-Black-Red-Brown)
73.2KX (Violet-Orange-Red-Red-Brown)
