PCM Questions for a Swap

I may be wrong, but I think the security deal occurs when the donor had a chip key. I have a 2004 Dakota, and it does not have a chip key...so I think you will be good. Are you going to use your existing harness? I have a low mile 5.9 from a 1998 3500 pickup that was a stick truck. I will be putting it in an 88 D100 with hopefully a 518 OD trans. I am going to use my existing harness that came with the motor and try to follow the tutorial that @TT5.9mag posted in another thread here. Good luck with your build!
