Yeah...I'm thinking I want to be in the 1200-1300 range, will get between 19500 and a 13000.I wont be running anything other than the heater or a/c...and also concerned with keeping away from wet stacking. Is there a certain hookup type I need? Such as...a special end or a type of plug? I am far from being any type of electrical guy...lol

Radio Shack has lots of resistors in stock, including a nice assortment pack for about $7. I went with 1/2 watt resistors.
By far the hardest part is connecting to the Upfitter wire stubs. I used Upfitter #4. Someone at Ford should be kicked in the junk for how short they made these wire stubs.

Some here are proposing pretty high RPM's for a high idle. Unless there is something specific which needs relatively high speed, 1100 rpm's is about optimum for stopping paraffin build up and producing heat and electricity while still maintaining some modicum of fuel efficiency. Even at 1100 you will notice substantial drops in overall fuel mileage but if fuel is not an issue, crank 'em up.

All I could find,without spending the whole day on it, was a package of 20k 1/2 watt resistors, That should put me in the 1100 range or so, I appreciate everyones help and input...great group of guys.

I'm in the process of trying to make this work. Are the 4 Blunt cuts just passed thru or are they hooked up to the upfitters under the hood. I can't locate them under the hood. And I'm not sure how the hell you hook to the passthru wires in the kick panel I can barely touch them.

Following, and thanks for the info, on the passthrough and upfitter wires. I will probably do this in my spare time. Had it on the last one. Might take me a few months to get up the nerve to cut wires.

When I get home from work in a couple weeks, I'm going to wire mine in. I think I won't use a passthrough wire though. It will be easier to install the resistor across terminals 9 and 10 in the cab by the kick panel, then just tap into the yellow/green wire on the C213 bundle where it comes into the engine bay under the hood with the passthrough wires. Tap into the wire there, run it over to an upfitter wire on the driver side under the hood, and call it a day.

I'm making progress. The fact that Ford did not run the pass thru wires to the upfitter relay box is beyond me. I'm doing this in between keeping the wife happy getting the house ready for Christmas so it looks like it won't get done for a couple more days.

Success
Ok. Worked on it for a few hours today. I used the BD High idle kit I had installed on my 13. It was the same color wire hookup as my 13. I verified with the Q 256 bulletin. The only hang up was there's 2 yellow/green wires on the SEIC / PTO Interface Connector one is for gas and one is for diesel. I had the gas wire hooked up for about an hour trying to figure out why it wasn't working. I hooked it up to upfitter switch 1.
