Running wires down A pillar?
 

Anyone have any advise about running wires down the left A pillar from the inner roof to under the dash. I don't see any obvious holes or routes.

Hey ya go... this is the hole behind the side of the dash. You might want to remove instrument cluster for better access or else you will be on your back under the dash.

Here is the top of cab with outer roof skin removed. You can see a quarter sized hole in the metal brace above the A pillar.

Assuming you have cab roof marker lights take them off and you have access to the wire.
