Argosy 24 rear roof vent replacement

I am in the middle of replacing my rear roof vent with a new [to me] fantastic vent. I already have the hole cut on the outer shell and will be cutting the inner tonight. The issue that I have having is that the old vent had rounded corners with a pair of power wires ran around. Since the new vent is squared I need to stretch those wires. Has anyone come across this at all? It did not feel like there was much room to give on these wires and I believe the vent is as far forward as I can get it without hitting the rib.



I need to use the RV on Friday for a 4 night trip so any advice would be appreciated! Thank you!
