I'm going to install some foglights on my 2000 1500, and I was wondering if there is an easy way or place to run the wiring through the firewall to the switch, which will be mounted somewhere on the left side of the dash. At first glance I didn't see anything but I didn't dig too deep. Any help would be appreciated.

 

there should be a spot where the wiring harness goes thru the firewall, that's your best bet.

another spot might be where the vacuum line for the climate control goes thru the wall...

 

Nothing to it. Just to the right of the power brake booster there's a great big rubber plug that is accessable from both sides, so I just shoved it thru there. Worked fine.
