Title: PCM or ECU
Post by: whitsend on January 07, 2025, 11:54:03 AM
Hi Gents,

Are these terms interchangeable when talking Gen III Hemi. If I'm looking to buy a used one what do i make sure the motor and trans includes? What wiring and anything else? Thanks in advance.  :notsure:

Check out the crate engines and harness from Mopar.  The harness kit shows what's needed for just the motor.
I used a 518, so I don't know what's required for the newer trans.

Bare minimum is PCM and PDM
