ECM swap

[Mark A]

Are you able to swap the ECU's from the trucks into a different year model truck. Mine is an 01 and I'll have a new 03 here monday but i want to keep my computer since it has the TTS reflash. Just want to be sure they havent moved any pins in the wiring harness before doing this.

Thanks,
Mark

Not that simple. ECM is tied to your 2001 VIN and Passlock code...

As John said, and on top of that there are some differences from '01 to '03, and the calibration from an '03 would not work correctly on your vehicle.

Sincerely,

James
