2009 Chevy Silverado Crew cab

[fireguy810]

I'm trying to find access into the cab of my 2009 chevy silverado crew cab. I need to run coax from the antenna mounted on the tool box. I can't find any holes to access into the rear of the cab. I also need to run a power wire through the firewall. Can't find any holes through their either. Any suggestions??

firewall has some rubber plugs on it, or go thru were your wires go thru and then water seal. coax can be routed under rear of cab. drill proper dia. hole, install gromet then coax. pull to length and then some and water seal around hole. also put a protective shielding around coax.

I don't know if the '09 has the vents in the back of the cab, but that is where I ran my coax thru- it can be REAL tricky!! I ran the power lines thru the BIG wire harness plug going thru the firewall.

Sent you a pm.

I have an 07 Silverado NBS and I had to cut the rubber grommet that houses the wiring harness on both sides and then feed the wire through the firewall that way. As for coming from the bed. Under the truck right before the frame rails on both sides right near the floor of the back seat there is a plug that you can drill out and then run the cable through, make sure you use ample amounts of silicone afterwards so you dont leak.
Have fun

Hi...I am in the process of installing my gear in a 2009 Chevy Silverado Crew Cab also. Just between the rear of the cab and the bed there are two vents each of which are located just behind the rear passenger doors....they can be hard to see and doubly hard to put hands on if your have mitts like mine. Anyhow I have succesfully run RG-8 through each using the bottom vent holes. I have left enough feedline so the vent cover (rubber) pretty much remains closed. I have located both an IC-706MKII-G and a FT-8900 under the rear passenger seat directly behind the driver seat and it fits very well. I still have to run power to the 706 but hopefully that will be completed either this weekend or next. I will try and post some pictures when all is complete.

Good Luck

if you lift the carpet up on the drivers side after you take the sill panel off you will see a wire already running through a grommet on the floor you can easily get an antenna wire through there. I always used this hole in gm's for rear view cameras on pick up trucks. As for the firewall there are many places to run wires through, there is also plenty room to make your own new hole or many grommets that are over sized with room to put a hole in and run a wire through. Good luck with install -JOEYD
