obd2 magnum swap?
I used the ECM from a 1998 Dodge 1500 Pickup with a 5 speed and no security. I bought it from Solo Electronics in Florida. It was reflashed to eliminate a lot of the functionality I didn't need. I also opted for the Hotwire Auto "hotrod" witing harness. It hooked up with 4 wires, was neat and located the ECM and fuse block next to the glovebox inside the car. It came with a e grommet to seal the wires at the firewall. It was plug and play.
I did have the injector connectors updated to run the more modern Ford 35lbs 2 hole injectors.
After it was in and running, I used Hemifever's tuner to adjust the mapping for my 408" Magnum Stroker. It's a beast.
