The data to read from this sensor is available on the J1939 data bus.
The fastest and cheapest way to read it would be to purchase a ScanGauge D. It will show boost and many other gauges that are on the databus.

You could also just get a boost gauge from Freightliner, they just plug into the gauges databus daisy chain. But it may require the dealer to activate the gauge.

Uncleal13, is that the bus used for most eld's these days?

Basically yes. The 9 pin plug that everyone is using has both j1702 and j1939 data streams on it.
Personally I would rather the ELD was wired into the databus under the dash. On a Cascadia there are many points this can be done.
As it is my ScanGauge plug falls out about once a week on rough roads, as it does not use a locking ring to secure the connection.
I wouldn’t want to be bouncing down the highway and have my ELD connection fall off.
