Another magnum swap thread
You're welcome. I'm going to stop by the little small town dealership where I bought my Dodge diesel truck, and see if they will let me look at a FSM for a 98 3500....which is what my 5.9 Magnum came from. I have every inch of the underhood harness, including the ECU and fuse/relay box. Thanks for letting me hijack/piggyback along here....lol.
Dragbaron.....thanks for the encouragement! Did you remove the wires in the OBD2 harness that went from the ECU to the gauges? What about the OBD2 hookup port inside the cab?
