I bought a 2007 300c with 140k miles for engine fir my 1955 Chrysler restomid. Since I intend to cobble my own harness, I thought skim would not be a problem. After reading more I think it will not run even with cobbled relays etc. until skim is disabled. Is that correct?

Welcome to the Hemi Swap Community! We want this to be an open forum where anyone can ask anything about the Hemi engine and doing Hemi Swaps. We find the information can be scattered all over the internet and want this to be a centralized place where we can talk amongst each other and share our questions and answers that may be able to help others going through similar Hemi swap situations. Please be kind to others and help out where you can while getting the information you need. Blake and Mike will be admins and answering questions here as well!
