Scalise

As title says, both ends of my third brake lamp (26590-4Z000) snapped off so it's just hanging there. I took both the 8mm bolts out and got under the truck lid to disconnect the cable. There's a seal plug preventing the cable from coming back through the spoiler. Do I just push this out with the light assembly? I imagine I'll have to fish the new one back through or should I just take the whole spoiler off the deck lid?
