Leer Topper Install

Recommended Posts

Hey guys, 


I ordered a leer 100XL topper for my 2021 3500 AT4. I installed it myself. It wasn’t difficult with the help of a few friends. The wiring was a little more tricky. The 100XL comes with the remote window lock feature. That was the tricky part. After a few days of research and development, I finally figured out which wires are the lock/unlock wires. If you take apart the drivers door sill, there is a covered wire bundle there. In that bundle, there is a 20 gauge gray wire and a 20 gauge brown/yellow wire. Those are the lock/unlock wires. Hope this helps people in the future so you don’t have to beat your head against the wall like I did.
