If you are going to the trouble of doing this don't limit yourself to just one rpm. Use a variable resistor (with a ****) so you can dial up whatever rpm you want. Mount it in an inconspicuous spot low in the dash or inside the center console. We still have 2 units rigged up this way.

They leave it to the aftermarket PTO suppliers, different PTO applications need different engine speeds to operate optimally so Ford supplies the EIC module that the aftermarket boys can utilize to best support their application. As far as factory high idle in cold weather it only idles up to around 900rpm and utilizing the EIC with an upfitter switch and a 19.5Kohm resistor will set the idle at ~1200rpm
Its Comin Right for us!

guys, would this work for variable? im not an electronics guru. chart on page 9 of the previously linked sve bulletin for elevated idle control says 1w resistor, 54k ohms would be the lowest speed of 900 rpm.

No expert on the subject but it should, but unless you are using multiple PTO applications that require different rpms variable idle control is not really needed. An idle of ~1200 is fine for extended idle situations which is where a single inline 19.5K resistor will set it.

I am getting ready to do this mod, I called my local dealer and they have a guy that has done many. I have to pick up a resistor,he said a 4700 ohm. Is there a particular brand,website I should order one from?
