Pulled the three cruise modules I'd been wanting to from the salvage yard today. All from 83 models oddly, one from a 300D, the other two w126's. An interisting note is that the two modules from the W126's, a 300SD and a gasser SEL, are the same part number in every way, identical. I figured a gasser would need different tuneing somehow.

Anyway, I broke out the new weller soldering iron and hit the w123 box. Stuck it in and boom, almost perfect cruise. I'm a happy boy.

I'd tested the boxes on the way home, none worked(surprise).
I plan on doing the two w126 boxes later to see if they happen to work. I don't know that they will work in a w123, as the PCB has slightly different componets, but I'll try it. Failing that I'll find someone with a w126 needing a module and see. I've had pretty good luck in soldering up cruise modules so far. My original went from dead to semi-functioning. I'm going to pull it agian and look it over too.

Maybe if this one lasts awhile I'll get to tryint to come up with a relay system to take the current load off that module.
