Cruise Control

I am wanting to install Cruise control on a 1997 F-350 Powerstroke. So far I have discovered that all the necessary wireing is there less the steering wheel. I know I need a different master cylinder, steering wheel insert and PCM. The truck is a federal (49 state) emmission truck with a 5 speed manual transmission. From what I have been able to find out so far is there is only 2 part numbers associated with the ECM, F7TF-12A650-SA And F7TF-12A650-SB, Can anyone tell me which one of these is cruise enabled or which part number in need to look for to get a PCM that is enabled?
If anyone can help me with this, i would greatly appreciate it. thanks

Cruise answers

I just Got mine it work, you dont need a new computer, Or a new master cylinder just the horn pad or... If your good with electronics and such you can do the way i did and spend $25 at radio shack for a few switches, resistors and wireing to make your own switch unit, foregoing the hasel of finding a different horn pad. As for the master cylinder, just jump the connector as described in previous post untill you have to replace the mastercylinder due to ware..

Cuise

I dont see how it even affects the master cylinder, all the pressure switch is for, that we are missing being we dont have the master cylinder for cruise, is a redundant switch to cancel the cruise if your brake on/off switch fails to cancel cruise when you apply the brakes.

PS, whats the 5.6k mod and where cani read about it?
