I don't have an ECM

If you're using a dodge 241 transfer case, apparently you can swap out the tailshaft portion of the case for a chevy one and get your speed signal from there.

Since the dodge dana 80 had a speed sensor for the RWAL system, I just used that as my speed signal and then converted that signal with a dakota digital box to calibrate my speedo. My cruise control is also ran off the same wire as well.

I'll have to dig into my schematics to see if I can eliminate the ecm all together like you did. if I don't need the ecm for cruise then all I need is a gasser cruise module and wiring. I was expecting I'd have to go with the DD converter boxes. I think 96 and down dodges still had a VSS on the tail shaft. I don't know when they made that switch.

On the both the 241d and 241DHD's 97 was the last year for it. 98 up 241d and 241dhd had none. They went to picking the speedo signal up from the speed sensor in the rear diff. Bit, you should be able to put the chevy stuff on the back of a dodge 241d. It's nice how universal new venture kept them.
