pcm swap.

Can anyone tell me if a pcm from a 92 Larado is compatible with a 93 Sport? Thanks

No. '93 is a bastard child that isn't interchangeable with anything else.

AFAIK

1991-1992 are interchangeable
1993 is unique
1994-1996 are interchangeable

I was really disappointed when I found this out, since my '94s PCM is only a few years old, I was going to hang onto it for a spare

Knowledge about these older Chrysler swap over years is getting hard to find.
I'm not sure even the 91 and 92 are interchangable, part number on the PCM seems to make a difference.

Thanks for the info. It always amazes me to see how they change things every year. The pcm's I have are different part numbers.

I've read that they are, but I can't confirm it. After checking Autozone it doesn't look like they do.
