Scangauge
At that point I started collecting some parts for a dual battery setup and going over options for sliders. In the meantime I installed a Scangauge. Very straightforward install, altho the Blendmount took awhile to get adjusted to fit as it was a 3 handed operation at times..
Here's the unit and the Blendmount mounting adapter:
Blendmount assembled and ready for test fitting, I used blue loctite on all the screws for the final assembly:
this is kind of a weird pic, but you can see the Blendmount collar and bracket attached to the rearview mirror stem:
Ran the CAT5 cable under the headliner, over to the driver side A-pillar, then down thru the dash:
And under the dash where it plugs into the CAT5 connector. Then the cable that came with the Scangauge is pugged into the connector and ran to the ODBII port. Had a bunch of extra cable, so after this pic I just coiled it up with a zip tie and tucked it behind the kick panel for now..
