2018 vs 2019 PCM swap

[shooterjgs]

Just received my unlocked PCM from Diablosport/Holley... I ordered a 3.6 Dodge Challenger PCM for a 2018 Dodge Challenger but the instructions are labeled "2019 Dodge cars T-2/I3" and step 2 says "with factory PCM installed ect..."
My understanding is that the 2018 is different in that all you do is remove old PCM and install the new unlocked PCM then tune or tune later... different from the 2019... Am I correct... I'm also now concerned that Holley sent me the correct unlocked PCM...

Edit: also how do I know its the correct PCM other than the invoice... any way to verify.

Problem resolved... Got up early this morning and talked to a tech with Holley (Rick) was very helpful and all is well now... Thanks
