Water damage, no wifi, on logic board

I am still limping along with no backlight or WiFi on my 3GS left in about an inch of water SIM end down overnight in a cup of water. I think I have the backlight nailed down to the #1 connector, will update after I try that fix.

Now I'm stumped on the WiFi (it's grayed out), I tested and the Bluetooth won't recognize a new device either. I ordered a WiFi cable, but I also swapped out and tried a different logic board. With the new logic board, the WiFi works--didn't check the bluetooth. The #6 connector looks OK on the old board. Is there hope on the WiFi and Bluetooth?

Thanks!
