Uhg made a nice whole long post and tried posting with pictures but no luck. Basically swapped the 2 sensors on the heads drivers side. Also changed the fpr since the fuel line elbow is bent 90* between the 2 engines so for peace of mind didn’t want to bend the fuel line. But came across 2 problems.
I have 2 wires that the labels fell off of and my pictures don’t show. Pretty sure smaller wire goes to starter as it reaches nicely and thicker wire is an engine ground.
Second problem is newer engine has what looks like an antifreeze tube that my older engine doesn’t have. I’ve tried numerous times to post a picture but it won’t post. The tube is on the passenger side of the engine under the bigger antifreeze tube
