It's gotta be the headlight switch right?

Ironracer. I see you posting onto old threads. My advice is to start your own thread.
Take your time typing it out, and edit as needed to make it easier on everyone trying to help.

If you want to reference older threads, hover your mouse over the post number, right click on the post number and select copy.
Then paste that in your post.

For example, this is a link to a post I recently made with description and sketch of the headlight switch wiring.
No power lights etc but ignition turns over?

As far as dimming goes. Lights dim when there isn't enough power available to supply them at the voltage when they were brighter. This might be normal or might be due to resistance in the wiring from the power supply.
Again I encourage you to start your own thread.
