My buddy has a 97 Cherokee and bought a 99 4.0 from a wrangler (thought it was from a Cherokee) I know we're going to have to switch up the exhaust a little bit but I was wondering about the electrical end of it. Will all the plugs plug back up the same or are their adapters we'll have to get? Do we just hard wire it? Are they all ganna be wrong? Just kinda curious what I'm about to get into.. Anything helps. Thanks guys. Going to be starting this project Friday evening so the more I know by then the better.
