2nd Gen 2011 Tundra XSP Headlight Assembly

Hello, I've searched the internet and this forum and cannot find the specific part # for headlights for this truck. Most all sites, including Toyota, claim the replacement #'s are 811500C051 or 811100C051. These have one less wire and plug attachment than my 2011 2nd gen XSP. Anyone had this scenario? I have 5 connections on the back of my headlight (4 lights and one connection). The toyota diagrams have 4 and do not show this extra connection. Pics attached.

 

I think the triangle fella is for the adjustable headlight beams on the tow package.

Is there perhaps a headlight adjustment dial on the dash to the left of the steering wheel? Wheel numbered 1 thru 5?

Aims the headlights down in the event of hauling heavy loads.

Replacement headlights would need to be built with the adjustment motors to retain this function.

 

Ok, that makes sense. I don't tow with this truck so wondering if I could just leave it unplugged?

 

I don't see any problem leaving it unplugged.

A lot of aftermarket headlights don't have motors/provisions and they function just fine... Only without the ability to level on the fly.
