Cant locate my PCM code?

Have a 2003 f250 7.3.

Im looking under my dash by the PCM, looking for a sticker somewhere. The wiring harness with the sticker and all and i dont see it anywhere.

I see a faded sticker on one of the harnesses but doesn't look like the code. Ive been looking for like 15 minutes.

Where is it?

open the hood take a 10mm socket and undo the plug/wire harness...its the plug closest to the drivers side fender. under the dash take the plastic case holding the pcm in and slide it out.

It's not under the dash. It's under the hood on the outside of the plug near the fender metal. I was able to see it with my kid's little makeup mirror and a flashlight. Smallish writing and it's hard to read backwards.

Well i couldn't locate it anywhere in the hood, even with a mirror , and removing that little harness part. I couldn't find it.

Didn't remove the PCM fully but i basically said screw it.

But i guess ill know where to look next time

Already sent my chip order in and they gave me my code so.

Check out this site. It may help you when you install the chip. This is also the location of the PCM Code. It is on the side of the thing that the 10mm bolt is on.

That link you gave me was perfect!

I was reading around that it was under the hood, then it was by the PCM under the dash and couldn't locate anything. But that link is great! and perfect for helping me install the chip!

By chance, does anyone know how far the switch will stretch, like how long the wires are?

Of course the PCM is under the dash but the topic of this thread is the PCM code and that is under the hood. It may have been easier for you to remove the PCM but to the rest of the folks that can just read the code from under the hood, it is much easier to leave the PCM installed.

My PCM code was exactly as it should have been according to the year/model of my truck. The risk is that some previous owner may have swapped it with the PCM from another truck with a different code.
