My buddy replaced is blown 2.3 with another 2.3 and got his wiring confused. I need a diagram of all electrical connections on the engine. For a 1997 Ford Ranger 2.3 manual transmission

 

Welcome to the forum

You really need a 1997 Ford Ranger EVTM(electric vacuum troubleshooting manual), Ford sends these out to all dealers each year for every model
You can find them on Ebay
Very detailed wiring, specific to that year Ranger, includes all engine/trans and options available that year
People buy them, use them then re-sell them so basically they are "free", lol, unless you end up with the VERY LAST running 1997 Ranger on the planet, then you will be stuck with it

I will post what I have, but its just for computer engine wiring, there are 4 pages
Ignore the automatic transmission wiring if you have a manual

 

I can only put 2 attachments per post, here are the other 2 wiring diagrams
