Wiring/ecm/pcm/etc. interchangeability?

Hey guys, I’m planning on doing a full magnum swap like @BadAss71 did in his 71 Dart. I’ll be in all the wiring, cluster, hvac, headlight switch, etc. I really like the horizontal hvac controls of the 00-01 Dakota over the vertical controls of the Ram/Durango’s.

So my question, would I be able to use everything out of a ram parts pickup but then use the dash harness from Dakota?

Obviously the ideal thing to do would be buy a 5.2/5.9 dakota and use everything from that but I have 2 neighbors that has a few ram parts trucks so I may be able to buy one for pretty cheap. (Haven’t asked yet.)

Thanks for any help!
