    My son just did a poor boy engine swap on a 95 Fld 120. He swapped a 11.1 series 60 into from a 12.7 after a lot of computer swapping and some wiring harness difficulties he finally cleared all the codes except one. My question... Where would the cruise control mechanical module be located?? It's not like it has a visible throttle and we dont know where to even start looking for it .....HELP would be greatly appreciated.

    Im not familar with the module you're asking about. If you're trying to get the cruise working that should be in the ecm unless it had an aftermarket cruise or is a freightliner part. Did you change ddec levels? Say from ddec 3 to ddec 2? I ask because the harnesses should be the same on 11.1 and 12.7.

    Sounds like the ECM is programmed for something that is not physically there. Cruise control switches will be wired inputs to the ECM. If you have changed the wiring around, or are using a different ECM you may need to get inputs properly programmed.
