Wire the grill lights to the headlights

A few question; I ordered a new front grill for my truck and it has 3 lights on it to be wired to something. There are no instructions so how do I wire it up. Also I ordered new headlights and plan to switch out the bulbs to led bulbs.

 

Please don’t run LED bulbs in halogen housings. You’re just going to blind oncoming traffic. Here’s a thread to improve your light output without blinding anyone: https://www.tacomaworld.com/threads/the-ultimate-headlight-upgrade-h4-not-led-or-hid.398066/

If I were to run a Raptor style grill with the amber lights, I’d wire them to the amber parking lights in the headlights.

 

Depending on the brand of "new headlights" and LED bulbs, you'll probably be pretty disappointed in the performance.
