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.
