06 Chevy Silverado Installation

[K3XLT]

Hi all:

I was wondering if anyone can help me with my situation. I just bought a Yaesu FT-8800 2m/70cm mobile and am going to install it to replace my Icom IC-2200H in my truck. I'm planning on mounting the control head at the dash and the main body under the back seat (my truck is a 4 door). My question is....Is there a good way to run all my wires and cables from the passenger compartment to the engine compartment.

For my 2200H, I ran all the wires out the drivers door and into the engine compartment along the inside of the fender. I owned a 03 F150 and when I was an Asst. Fire Chief, I installed my fire mobile and by taking off the passenger side kicker panel, there was a nice hole to run the wires/cables through and just thought I would ask if anyone knew if the Silverado had the same kind of set up, before I remove the panel and other trim for nothing. Thanks.

I have yet to see a late model (1985-present) without a plethora of removable rubber bulkhead plugs in the firewall. Sometimes they do require some looking before you can see them... be prepared to do some crawling around with a flashlight, maybe even temporarily detach the footwell carpeting from the firewall, and I'm sure you'll find several very suitable feed-through points.

What I have done on my older pickup is to take a 3/4 hole saw the same as for drilling antenna holes in the body and drill such hole through the fire wall. When the hole is there then take a rubber 3/4 hole plug and put in the hole and then you can put a cut into the plug and run the cables through to the battery etc. As key2 indicates there should be available holes but if not try my example works well keeps dirt etc out but allows fires to be fed through the firewall.

i have a couple of the rubber plugs through the firewall on my 99tahoe - i have my pa wires running through it.

on the GM, check behind the radiator overflow tank on the passenger side or just above the brake on the driver side. There should be a plug on both sides. Some of the 4 doors also have a rubber plug under the passenger seat floor.

On 99-07 classic GM trucks, there is a factory dimple (centerpunch) located on the firewall, facing the engine side, near the 3-o'clock position of the brake booster. You can drill thru that (after checking to see if anything is in the way!) towards the passenger compartment, and protect your wires with an appropriate grommet.
