I got my new Autometer "A" pillar triple gauge mount today with gauges and was wondering how you guys got the wiring and tubing through the dash? I am guessing drilled a hole somewhere to manipulate the wires and such through? I am going to try to install the Trans. Temp, Boost and Oil Pressure this weekend hopefully, if things go right.

 

Thanks for help!

No need to drill holes.  Take the cover off the left A-post and there should be an opening between the left side of the dash and the body.  You can run every thing through there.    

You will see the wires running down to the firewall grommet through the fuse panel cover as well.

What they said, I ran the cables for my CTS2 screen and backup camera through that gap as well.
