Just got my 02 ZR2 and now it's time to move my ham radio from the truck to the Blazer. Is there a 12v access point under the dash? If not, then what would be the easiest way to route through the firewall to the battery?

Thanks all!

 

Easiest way... if you look under the dash on the passenger side, you will find a rubber grommet, that has one solid wire going through it, that is the radio antenna wire. That is about the best area to have just about a straight shot to the battery.
That is where I ran my power wire for my amp.
I wish I could describe where this rubber grommet is exactly.
Its closer to the center console than it is to the kick panel about 2" down for the bottom of the dash.... if that makes sense.

 

Depending on how much power it pulls, you could just tap into the radio batt feed.
