You want to find the switched 12V wire in the fusebox under the hood... Driver's side. The Umnitza brand also came with a "trigger wire" that you run into the passenger side footwell and attach to the interior footwell dome light. I assume that you could do the same.
I bought the LED type though... They are bright as sh1t!
If you search here and on YouTube you will see installation videos... They are very helpful. They will also show you the correct switched wire to tap into.
Hope this helps.
