Stupid question?

there are no stupid questions. I have not done the mod, but my understanding is the ICP (injection control pressure) sends a signal to the PCM (powertrain control module). the 10K mod makes that signal weaker, causing the PCM to send more oil pressure causing more fuel to be injected. (i.e. ICP sees 1200psi, and sends that signal 10K mod reduces signal PCM thinks ICP sees 900 psi, PCM opens IPR (injection Pressure Regulator) ICP sees 1500psi PCM recieves 1200psi signal and is happy.

Yeah
It's a simple mod thats almost like a chip. It will give some better power and torq with out costing you your wallet and your first born. I have done it myself and it works pretty good. You can always try it and if you dont like it then you can take it out.

Did someone say recently that you can stack it with a chip or does it just duplicate the result? How hot a chip can you go before the 10K mod has no effect? I'm guessing it will also stack w/ the FPR BB shim too.

the only stupid question is the one not asked, don't be afraid to ask anything. welcome to fte. stacking with chip?, i dont know. stacking with fpr shim, perfectly ok. i just did my 10k a couple of days ago. i wired it through the firewall to a switch i mounted just left of the drivers right side a/c,heat vent. i've read posts claiming 30hp gains. i don't know. i must not have a good attention to detail because i can't really tell a difference in performance. i also didn't notice any difference in the fpr shim. this is not to say the difference is not there, i just might not be noticing it. when i hit the switch at idle the rpms go up just a bit then settle back in when the pcm adjusts. the higher oil pressure for injection actuation brings the idle up. i like to think that it is adjusting back fuel rate to bring the rpms down therefore saving me fuel. i just finished off the front tank today post mod and will be filling up and checking fuel mileage difference tonight. we'll see

What do I have to do to get a 10 k mod?
Componets or wiring diagram?
Exactly what do I have to do to get it to work?
I own a 96 ford f-250 7.3 turbo diesel with 187,000 miles, free flow exhaust and cold air intake

The plug pins the male and female connection pins
How do they not touch when the plug is reconnected?
I get the resistor part but when you plug the connector back together does it bypass the resistor through the original connector pins

I have done the mod and it didn't seem to make much of a difference at first but after I drove it for awhile I started noticing it. I can also tell because there is smoke out the back now when before there was none. Also I don't think you will tell any difference with the BB mod.
I would also like to know how it compares to a chip, can I use it with a chip, how big of a chip before it is useless, etc.?

actually it makes more resistance. i said least resistance because i used to think that the resistor had to be inline with one of the existing wires if the electricity would just go across the pins like you said since that seems like the "path of least resistance". again i can explain electrical theory. i understand it ok, just cant teach it. the pcm sends a five volts to one of three pins. the other two are a ground and a signal voltage wire. the sensor allows more or less of that constant 5 volts to return as signal voltage to the pcm depending on how much pressure is there. when u install the 10k ohm resistor you have lessened that signal voltage returning the ecm "tricking" it into reading less pressure than is actually there. the pcm then raises the oil pressure used to inject the fuel.
