OBD1 PCM interchange/compatibility, 5.2 vs 5.9

Could be that RammerJammer75 got you mixed up with me.

I do have a ‘91 Dakota with the TBI 318 that I am (slowly) working on converting to a Magnum 5.9 and I posted a couple of comment earlier in the thread about what I’ve discovered about the convention.
No, I was actually speaking to the OP first. I just got a year ahead of the Magnum release lol
