5.9 into '72 Scamp- search not helping...

JDMopar,
You just gotta find wiring diagrams for that '98 Ram and start looking at what can be removed from the harness. I got mine from Alldata. Once your done you'll be down to two wires to connect to your truck (other than grounds), a power wire to the computer, and a power wire to the fuel pump.

You'll need a flexplate from a 5.9 magnum motor, and a crank sensor for an automatic equipped Ram(different lengths between auto and manual crank sensors). PCM won't care about what trans you have with it being for a manual.
