I didn't take any pictures or video, but the new motor fired up last night. We struggled a bit with the wiring, and I'm blaming one of the connectors that came in the harness with the 4.0.
I'm not sure if we had a section of harness from a different vehicle mixed in with what I got with the motor, or if jeep actually had 2 completely different sections of harness with the exact same plug. Either way, once we figured out and fixed that we weren't sending power to the green and orange wire, that basically powers everything, it started right up.
The motor sounds great, good oil pressure, etc. We have a few things to button up this morning, and we are planning on heading for a test ride at gulches this afternoon.
