ECM Location?

I have an E99 F350, 7.3, SD, CC, DRW. I'm installing an exhaust brake and I need to hook some wires up to the ECM. The only thing is, I don't know where the ECM is? A little help from a PSO guru will be highly appreciated.

My '01 it's inside the cab under the dash up next to the parking brake assembly. The cable attaches throught the fire wall below the Master cylinder. Not sure on a '99.

Isn't that the PCM? At least that's where I plugged the chip in. There is another set of plugs right next to the PCM plug, but a little more toward the center of the firewall. They're the same type of large plug as the one for the PCM, though a little different of course.

K - I must not know what an ECM is. Sorry - didn't mean to confuse the situation.

Well don't feel too bad about it, I don't know either. Dang I miss the old days . All I know is that ECM stands for Engine Control Module, and PCM stands for Power Control Module. Outside of that, I don't have a clue.
