Here's three pics of the plug on the rear of the entire towards the fire wall. On the right of the pictures is the oil pressure sensor. Up top is the knock sensor. in the last picture the starter is on the left.
Here are the contents of the kit.

The heater from the side. It comes with that bit of Teflon on it. I put more on before installing.
The box.
Directions.
You're going to need a 12mm hex bit to remove the plug in the engine.
Plug is removed.
The heater with copper washer is installed hand tight.
The directions say to use a 24mm socket to tighten. I found an American 1.25" socket (I think!) fit much better. This is what took me a while because I didn't have the best tools for the job. I think a short 1/2 drive extension would have made it so I could have used a torque wrench instead of a breaker bar.
The power cord plugs into the heater and runs back towards the fire wall. I made sure to leave some slack here when I tied it down at the firewall side to allow for engine movement.
This picture is looking directly up at the bottom of the intake manifold. Here the cord is going from the heater (hidden in the bottom right) back towards the firewall. I made it purple for easy finding.
I decided to route it around the steering rack this way. I tried to avoid running it anywhere that would require it to be removed during any maintenance.
I looped it tight behind the engine support cross member.
I have the cord running along the cross member.
I tied it off with a zip tie towards the front of the cross member.
I didn't follow the directions for the routing of the power cord, but I felt this would be best for me.
Hope that helps.
