I can't find the data link connector.
...on a 98.5, where does the supplied banjo bolt go? Kit comes with one, but it shows two locations.

 

The data link is in the front of the motor on the driver's side. You will see two unused plugs with caps in them. You will use the triangle grey plug. It will look just like the edge end. Edge shows for 98.5 to put the sensor on top of the fuel filter. My 99 I put it on the injection pump. I don't see what the difference is?

 

I found the 2 unused connectors but they don't fit the harness or the adapter that came with it.
