ScanGauge II displays the 5-character error code(s) associated with a check engine light.  I can “pull the codes”, make my own repairs, clear the codes and turn off the check engine light.

Most usefully, with its exclusive X-GAUGE™ programmable gauge system; I can monitor parameters such as transmission temperatures, trip data and fuel economy information. Here is x-gauge code from ScanGauge II website for my truck.

I wanted to install ScanGauge II somewhere that it does not block other vital displays.  Unit has two RJ-45 style jacks – one on the side and one on the back so you get some choice of cable location. Here are step by step instructions:

1.  Remove the cover of ScanGauge II.

2.  I picked up two cheap measuring tapes from a dollar store for their clips.

3.  Remove the clips from the tape measures, and find a good spot on the top face of the back cover of ScanGauge II so that screws has enough clearance.

6.  Unit comes with 6 feet connector cable. After connecting it to OBD II port under the dash, near the steering column, remove the driver side pillar cover with 10mm socket and run the cable behind it.
