I found it today. In order to potentially help someone else here is where I found mine.
In the garage the low voltage panel is to the left of the breaker box.
On the outside of the house, the low voltage panel would be to the right of the electric meter box (if you could see it) because the meter box is directly behind the breaker box.
The house ground comes out of the bottom of the meter box probably close to the middle (left to right) of the meter box.
Using a small hand garden shovel, carefully dig around the grounding conduit. Once you dig down, there should be a green ground wire that has a warning not to disconnect on it. This will be the ground wire that is connected to your TV cable in the low voltage cabinet. Follow that wire. It will lead you to the external conduits.
Assuming all low voltage panels are a foot or so away from the breaker box inside, the external conduit outlets from the low voltage box should be within a foot of the house ground conduit and about 12 - 18 inches deep.
I ran my new wire in one of the empty conduits. However, that conduit was plugged with dirt up to about 4 inches in so I had to use a screwdriver to dig the dirt out.
Hope this helps someone. Oh, I needed the new wire to connect a flowmeter to my irrigation water line so my Rachio 3 controller can notify me if there is excessive water use as when a sprinkler head is damaged and needs replacement or when there may be a leak.
