Question Headlight dimmer wire ?

I am installing an Isspro Pyrometer on my 2019 & I need to tap into the dimmer wire. What wire behind the headlight switch am I able to tap into for dimmer control of the pyrometer?

In post #26 of this thread, JoeUser talks about tapping into the low beam wire. Perhaps he can help you out.

In that thread he stated he taped into the low beam head light wire under the hood near the headlight. I’m looking for the wire for the dimmer on the back side of the headlight switch on the dash.

Thank you for attempting to help. I appreciate it.

I don't have the answer but found the electrical manual on ebay. https://www.ebay.com/itm/255271496650

EDIT: I just found the same for my '21 which is half the price and ordered it. I don't know if it would be correct for the '19 on that circuit specifically but it might be. If you want to wait a while I can scan those pages when it comes in.

If your handy with a multimeter, you can use a paper clip and multimeter to find the wire on your headlight switch connector. with it connected to the switch, the voltage will very as you roll the thumbwheel...when your on the correct wire.

Are you wanting to know what wire to use to backlight your gauge, so when you turn your lights on the gauge will light up?

Thank you for the tip. I figured it out using my multimeter.
The wires seen on the back of the headlight switch are different colors from the OEM wiring due to I have a 12 volt solutions remote start system install. The wire location is the same as OEM.

Thank you to all that responded & helped.
