Hi, Greg! Welcome to TRS. We have a whole forum section for engine swaps and the 5.0l is a popular one. One of the smartest things you could do is order the EVTM (Elevtrical & Vacuum Troubleshooting Manual) for your Ranger and also the one for the donor vehicl your engine, ecu, wiring harness, etc. Is coming from. That way you have the exact diagrams for each one for comparison.
Also, pick a suitable place, like
Here and start a build thread. That way, you can document your project and keep all the questions, answers, pictures, etc. In one place instead of starting threads all over the place every time you have a question. It keeps things organized - for you and for us.
