How to thread microphone wire from behind stereo to A pillar

I have my microphone mounted on my rear view mirror. Running the wire under the top headliner panel, down the a pillar, now I'm wondering how to get from the base of the a pillar to the head unit plugin ?

 

i mean.. wouldn't you just go behind the dash?

 

Run it down the pillar under dash ,along the bottom of the dash and take a speaker wire or coat hanger and fish the mic wire up to radio.

 

You didn't mention if you removed the A pillar trim panel. If you have not, it's really easy and then you just poke the wire down through.

Pop the 2 caps out of the grab handle. Use a 10mm socket to remove the 2 bolts. Remove the handle. grab the trim at the top and pop it out. Pull upward on the trim. After that, it's easy to poke the wires down through.

 

Finished! Popped the instrument panel out and ran it behind the speedometer . Stoked !
