Im trying to help a buddy out with his 89 wrangler with a258 and a 2100 swap. A buddy of his did it for him and never finished it. I have found many diagrams online about which lines you need and where to run them. But nothing about all the emissions crap on the valve cover and what needs to be hooked up or removed. Also where is the vacuum line for the 4wd need to be hooked up at. I can not believe the mess under the hood and i get thrown into the middle of it! Any help would be appreciated or pics or anything!
