My headlights are working when i turn them on with the switch but my cluster lights and the lights for my boost and egt gauge arent turning on with the switch. I checked fuses but i didnt see a fuse specifically for the cluster. Is this a bad headlight switch? Where can i buy a new one? Or am i gonna have to get a used one?

 

Check your dimmer switch.

I had the same issue and I checked relays and connections BUT to my surprise the interior dimmer switch was the issue.

Is there a way to test it?

 

Well my lights decided to work last night hahah all my cluster lights worked fine and everything! Any idea why it would do this??

 

It's not the headlight switch. Why would you suspect the switch? Electrically it does not.distribute power to all the things you mentioned. Thats jumping the gun a bit.

Get the dimmer roller switch and roll it up and all the way down really fast. The potentiometer contacts are probably just old and worn or dirty inside.
