Power Extension to Dash Top

[H3.007]

Hi All,

Has anyone ran aftermarket wires down through the dash? I see there is a cap on the drivers side over the hole that contains the sensor in the passenger side. Would this be a way of running a power extension from the top down to the bottom to connect into the das power outlet? I want to install the extensions so I can mount gear on the dash without having to hard wire everything.

Thanks!
