The schematics should show the switch, all you'll need to do is connect the power to the 6V from the heaters and the SW contacts to the jack.

"Bob,

I also have a Weber switch board. However, I was confused when I read that I should short the tip and the ring to engage the switch and not ground either of them. Wouldn't I need an isolated stereo jack to accomplish this? As far as I know the regular jacks on a Fender are not isolated from the chassis.

Any help would be greatly appreciated.

Best regards,
